Fraction to-decimal
A fraction (from Latin fractus, "broken") represents a part of a whole or, more generally, any number of equal parts. When spoken in everyday English, a fraction describes how many parts of a certain size there are, for example, one-half, eight-fifths, three-quarters. A common, vulgar, or simple fraction (examples: 1 2 {\displaystyle {\tfrac {1}{2}}} {\tfrac {1}{2}} and 17/3) consists of an integer numerator displayed above a line (or before a slash), and a non-zero integer denominator, displayed below (or after) that line. Numerators and denominators are also used in fractions that are not common, including compound fractions, complex fractions, and mixed numerals.
The numerator represents a number of equal parts, and the denominator, which cannot be zero, indicates how many of those parts make up a unit or a whole. For example, in the fraction 3/4, the numerator, 3, tells us that the fraction represents 3 equal parts, and the denominator, 4, tells us that 4 parts make up a whole. The picture to the right illustrates 3 4 {\displaystyle {\tfrac {3}{4}}} {\tfrac {3}{4}} or ¾ of a cake.
Comparing and ordering integers
An integer is a whole number that can be positive or negative, including numbers like 12, -10, and -30,843. Fractions and decimals are rational numbers, not integers. Integers are plotted on a number line and can be ordered from least to greatest or greatest to least. The absolute value of a number represents its distance from zero on the number line and is always positive.

The same steps are used for discounts, but the discount amount is subtracted from the original price. An example problem at the end calculates the final price of a coat that was originally $75, marked down 10% and then an additional 30% off, plus 9.75% sales tax in Tennessee.
Lesson 6.9
The document provides examples and explanations for calculating markup, discount, and sale price based on cost or regular price. It defines markup as the amount added to the cost to arrive at the selling price. Discount is defined as the amount of price decrease during a sale. Examples are provided to demonstrate calculating markup and discount percentages, as well as determining selling price or sale price from original cost or regular price.
Chapter6.6
This document provides examples for calculating percentages related to commissions, sales tax, earnings, profit, and total sales. It includes steps for setting up equations to solve for unknown values when given percentages and totals. Examples calculate commissions earned by real estate and car sales agents, sales tax amounts, percentages of earnings withheld for taxes, profit earned from a percentage of total sales, and total sales when given a profit that is a percentage.
Lessons 6.8 And 6.9
The document discusses calculating percentages of change, including increases and decreases. It provides examples of calculating the percentage of increase from an original to final amount, and the percentage of decrease. It also discusses calculating markups and discounts as percentages. Markup is the amount or percentage by which a store increases the price above its cost. Discount is the amount or percentage by which the original price is reduced.
Fractions Decimals And Percents
The document discusses various math concepts related to fractions, decimals, and percents including:
1) Converting between fractions, decimals, and percents.
2) Calculating percentages of amounts by multiplying the percentage decimal by the original amount.
3) Examples of word problems involving sale discounts calculated as percentages of the original price.
Mark Up And Discount
The document discusses calculating markups and discounts for retail stores.
It provides examples of calculating markups based on a store's cost and its percentage markup. For a music store with a 67% markup, a CD that costs $10.50 would have a $6.80 markup.
It also discusses calculating discounts, with an example of a 20% discount on an item originally priced at $39.95 resulting in a sale price of $31.96 using either a two-step method or a one-step method.
The document concludes with assignment problems for the reader to complete related to these markup and discount calculations.

How to Manage Reception Report in Odoo 17
A business may deal with both sales and purchases occasionally. They buy things from vendors and then sell them to their customers. Such dealings can be confusing at times. Because multiple clients may inquire about the same product at the same time, after purchasing those products, customers must be assigned to them. Odoo has a tool called Reception Report that can be used to complete this assignment. By enabling this, a reception report comes automatically after confirming a receipt, from which we can assign products to orders.

Discount and sales_tax_ppt
- 1. Objective: Students will be able to solve problems involving discounts and sales tax. VOCABULARY: A discount is the difference between the original price and the sale price. A sales tax is an amount added to the price of a purchase.
- 2. A discount is the difference between the original price and the sale price. Ms.Thomas bought a dress. The original price was 78, and it was discounted 30% off. 1. Find the discount What is 30% of 78? Change % to decimal and multiply 0.3 • 78 = 23.40 discount 2. Subtract the discount from the original price. 78.00 - 23.40 54.60 is the sale price
- 3. A discount is the difference between the original price and the sale price. Lou found a bat that had an original cost of 125, but it was marked down 20%. What is the sale price? 1. Find the discount What is 20% of 125? Change % to a decimal and multiply 0.2 • 125 = $25.00 discount 2. Subtract the discount from the original price. 125.00 - 25.00 100.00 is the sale price
- 4. A sales tax is an amount added to the price of a purchase. A hotel cost $158 per night plus 11.3% sales tax. What is the total cost per night? 1. Find the tax What is 11% of 158? 0.11 • 158 = 17.38 sales tax 2. Add the sales tax to the original price. 158.00 + 17.38 175.38 is the total cost
- 5. A sales tax is an amount added to the price of a purchase. You buy a stereo for 387.50. What is you total cost if the sales tax is 7.25%? 1. Find the tax What is 7.5% of 387.50? 0.075 • 387.50 = 28.09 sales tax 2. Add the sales tax to the original price. 387.50 + 29.06 416.56 is the total cost
- 6. Sally found a sofa that had a price tag of $450. It was marked 35% off. What is the total discount? Sally decided to buy the sofa that was on sale. The sales tax is 8.5%. Find the total cost of the sofa. YOU TRY IT!
