What is Ratios?

Ratios are comparisons of two quantities. They can be written in three ways: as a fraction, using the colon symbol, or as a verbal statement. For example, if there are 3 red marbles and 5 blue marbles in a bag, the ratio of red marbles to blue marbles can be written as 3:5, 3/5, or "3 to 5".

Ratio & Proportion

Ratios are used in proportion problems to compare quantities and find missing values. Proportions are equations that state two ratios are equal. For example, if 2/3 = 4/x, we can solve for x by cross-multiplying to get 2x = 12, and then x = 6.

Chapter Notes, Class 8, Maths

In Class 8 Maths, students learn about ratios and proportions as fundamental concepts in solving mathematical problems. They also learn how to simplify ratios, convert ratios to fractions, and solve proportion problems using cross-multiplication.
