This document provides an overview of fundamental arithmetic operations including fractions, ratios, proportions, and percentages. It defines key terms such as numerator, denominator, proper/improper fractions, equivalent fractions, and operations involving addition, subtraction, multiplication, division, and powers of fractions. It also defines ratios and proportions, including using cross multiplication to solve proportion problems. Finally, it discusses percentages and how to convert between fractions, decimals, and percentages by moving the decimal point.
This presentation is about Cash and Trade Discounts. The formulas, examples, and definitions. Hope you like it. This is the thing that I used when I had my teaching demo in Bookkeeping.

A basic understanding of decimals and percentages is key to any businessperson, whether tallying costs for warehouse supplies or estimating resource allocation.
Therefore learn to use decimals, addition, subtraction, multiplication, and division; and to solve problems involving percentages.
Also, knowledge of ratios and averages is indispensable in the business world. Using real-world scenarios, this course explains the concepts of ratio, proportion, and how to compare different kinds of numbers; and discusses simple, weighted, and moving averages.

Francesca Gottschalk - How can education support child empowerment.pptxEduSkills OECD
Francesca Gottschalk from the OECD’s Centre for Educational Research and Innovation presents at the Ask an Expert Webinar: How can education support child empowerment?
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
Acetabularia Information For Class 9 .docxvaibhavrinwa19
Acetabularia acetabulum is a single-celled green alga that in its vegetative state is morphologically differentiated into a basal rhizoid and an axially elongated stalk, which bears whorls of branching hairs. The single diploid nucleus resides in the rhizoid.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

To solve problems dealing with proportion, we use
cross multiplication.
Types of proportion:
Direct proportion
2.
If increase or decrease at the
same rate.
E.g. If we buy rice at RM 2 for 2
kg, then we expect to pay RM 4
for 4 kg.
Inverse proportion
If an increase (decrease) in one
quantity produces a decrease
(increase) in a second quantity
in the same time.
E.g. 5 men building a wall take
20 days. If 4 men, it will take
only 25 days.
