2. Fractions can be represented on a number line, where each increment represents another equal part of the whole. Common fractions include halves, thirds, and quarters.
3. Fractions are used in everyday situations like baking, where recipes call for measurements like 1/4 cup of an ingredient. They help describe portions or percentages of a whole object or quantity.
Fractions
Fractions represent parts of a whole. They are made up of a numerator above a denominator, where the numerator indicates the number of equal parts being considered and the denominator indicates the total number of equal parts the whole was divided into. There are three main types of fractions: proper fractions where the numerator is smaller than the denominator, improper fractions where the numerator is larger, and mixed numbers which are a whole number and a fraction combined. Fractions are used to represent parts of measuring tools like rulers and cups as well as in other mathematical concepts.

Fractions
Fractions represent parts of a whole. A fraction consists of a numerator above a denominator separated by a fraction bar. Fractions can be proper if the numerator is smaller than the denominator, improper if the numerator is larger, or mixed numbers consisting of a whole number and proper fraction. Equivalent fractions have the same value even if represented differently, and fractions can be reduced to their lowest terms, simplified, or changed between improper, mixed, and proper forms through multiplication and division.

This document contains 10 sentences that require analysis of their grammatical structures and identification of any errors. Participants are asked to discuss the basic structures in each sentence such as subjects, verbs, prepositional phrases, and appositives. For questions 7-10, participants must choose the correct answer to complete each sentence.
Adjective after linking verbs
This document discusses the difference between adverbs and adjectives when they follow linking verbs. It provides examples showing that linking verbs like "look", "seem", and "feel" are followed by adjectives, not adverbs, because they link the subject to a description. Common linking verbs are listed along with examples of their use with adjectives. An exception is noted that an adverb can precede an adjective following a linking verb.
The passive introduction -
The document discusses the difference between active and passive voice in English sentences. In the active voice, the subject of the sentence performs the action stated by the verb. In the passive voice, the subject receives the action instead of performing it. The passive voice uses a form of the verb "to be" along with the past participle of the main verb. It also typically includes the phrase "by somebody/something" to indicate who or what is performing the action on the subject. Examples are provided to illustrate these characteristics of active and passive voice constructions.
Adjective and adverbs
Adjectives describe nouns and usually precede the nouns they modify. Adverbs modify verbs, adjectives, or other adverbs. When an adverb modifies a verb with an object, it should not be placed between the verb and object. Most adjectives precede the nouns they describe. The document provides examples of correct and incorrect placements of adverbs and adjectives in sentences.
Nouns don't confuse persons with things
This document provides examples of errors that can occur on TOEFL exams related to confusing nouns that refer to persons versus things. Specifically, it notes that in some examples the noun used should refer to a thing or career instead of a person. The examples shown are meant to illustrate this type of error, where the noun "authoritarian" should be "authority" referring to Ralph Nader as a person, "accountant" should be "accounting" referring to a career or field, and "nurse" should be "nursing" again referring to a career rather than an individual person. The document emphasizes to always check that the correct noun form, whether referring to a person or thing, is used.
Verb agreement inverted subject-verb
This document discusses verb agreement in sentences with inverted subject-verb order. It provides 5 situations where the subject and verb are inverted: 1) sentences beginning with a negative word, 2) sentences beginning with a place word, 3) direct questions, 4) conditional sentences beginning with "had", "were", or "should", and 5) comparative sentences using "than". It emphasizes that the verb and subject must agree in number and stresses common errors in questions with inverted subjects seen in the TOEFL exam.
Other types of words prepositions
This document discusses how TOEFL questions test the use of prepositions. It notes that prepositions can have literal or idiomatic meanings, and the TOEFL often tests the idiomatic use. It provides examples of incorrect prepositions, such as "called on" instead of "called off" and "count in" instead of "count on". It also gives examples of sentences missing prepositions, like "wait me" instead of "wait on me" and "plan attending" instead of "plan on attending". The document emphasizes being able to identify both incorrect prepositions and missing prepositions in sentences.
English 100 error detection & correction for all exams by das sir(09038870684)
This document provides 65 tips for correcting sentences in English related to subject-verb agreement, uses of participles and infinitives, uses of verbs, uses of adjectives, and uses of adverbs. Some key points include: subject-verb agreement depends on whether the subjects are singular or plural; participles must have a subject of reference; certain verbs like advise are followed by an object and infinitive; adjectives show quantity, number, or degree; and adverbs modify verbs, adjectives, or other adverbs. The document aims to help with grammar corrections needed for exams.
Parallel comparatives
This document discusses parallel comparatives and provides examples. It explains that when using comparative adjectives in the same sentence, each phrase must begin with "the + comparative" and be separated by a comma. This structure is used to show proportionate increase or decrease between the two things being compared. Four examples are given that follow this pattern of "the + comparative" separated by a comma, such as "The older we grow, the wiser we become."
Verb tense time expressions
This document provides guidance on using time expressions to determine the correct verb tense in a sentence. It explains that certain words or phrases that indicate when an action occurred, like "last week" or "by the time", are linked to specific verb tenses. The document then lists common time expressions and the verb tenses they correspond to, such as using the present tense with expressions like "every day" and the past tense with expressions like "yesterday". It concludes with examples that demonstrate how to match different verb tenses with time expressions.
Verb tense use have and had correctly
The document discusses the proper use of the present perfect and past perfect verb tenses. The present perfect tense uses "have" or "has" with a past participle to refer to an action that began in the past and continues to the present without a specific time. The past perfect tense uses "had" with a past participle to refer to an action that occurred before another past action. It provides examples of each tense and notes they must be used correctly with other verb tenses, with the past perfect combining with a simple past tense and the present perfect with a simple present tense.
Verb agreement prepositional phrases
When answering "Find the error" questions on the TOEFL, follow these steps:
1) Identify the subject and verb in the sentence.
2) Remove any prepositional phrases, as they provide extra information not relevant to subject-verb agreement.
3) Check that the subject and verb agree in number - a singular subject requires a singular verb and vice versa. Prepositional phrases can sometimes separate the subject and verb, so ignore these and focus on agreement between the stripped-down subject and verb.
Eng9 determining word origins
This document discusses different ways that new words can be formed, including clipping, blending, compounding, acronyms, and folk or popular etymology. It provides examples for each method of word formation, such as "phone" being formed from clipping "telephone" and "smog" being formed by blending "smoke" and "fog." The document also discusses the study of word origins and histories called etymology.
Parallel comparatives
This document discusses parallel comparatives, which show proportionate increase or decrease between two things. Parallel comparatives follow the structure "the + comparative expression + subject + verb".

2) Expressions of quantity like "all", "some", and "most" are usually followed by "of something", where "something" refers to the item being described. The object after "of" determines if the verb should be singular or plural.
