DEFINITION OF RATIO -

A ratio is a mathematical relationship between two quantities or values that compares their sizes or magnitudes. It is typically expressed as a fraction, with one quantity (the numerator) being divided by another quantity (the denominator). Ratios are often used to compare two or more quantities or to describe the relationship between them.

In its simplest form, a ratio is written as:-

Numerator

Ratio = -----------------

Denominator

For example, if you have 3 red marbles and 5 blue marbles, you can express the ratio of red marbles to blue marbles as:

3

Ratio = --------

5

Ratios can also be expressed in different ways, such as in the form of percentages, decimals, or fractions. They are commonly used in various fields, including mathematics, science, finance, and everyday life, to make comparisons and analyze relationships between quantities.

In its simplest form, a ratio is often written as "a:b," where "a" and "b" are two numbers. For example, if you have 3 red apples and 5 green apples, the ratio of red apples to green apples can be written as 3:5.

In a ratio:-

• The numerator represents the part or quantity being considered.
• The denominator represents the whole or the total from which the part is taken.

Ratios are used in various fields such as mathematics, science, finance, and everyday life for making comparisons, analyzing relationships, and expressing proportions. They are a fundamental concept in mathematics and are used to describe the relative size or magnitude of two or more quantities.
