## ratio

### In mathematics, a ratio represents the relative sizes or quantities of two or more values

In mathematics, a ratio represents the relative sizes or quantities of two or more values. It is a comparison of two numbers or quantities expressed as a fraction or division.

The ratio of two numbers, A and B, is typically written as A:B or A/B. The numerator (A) represents the first quantity being compared, while the denominator (B) represents the second quantity. For example, if we have 4 red apples and 6 green apples, the ratio of red apples to green apples is 4:6 or 4/6, which can be simplified to 2:3 or 2/3.

Ratios can also be expressed in decimal or percentage form. For instance, the ratio 2:3 can be written as 0.67 in decimal form (by dividing 2 by 3) or as 67% in percentage form (by multiplying the decimal equivalent by 100).

Ratios are commonly used in various mathematical applications, such as proportions, scaling, and comparisons. They are used to describe relationships between quantities and can be useful in solving problems involving rates, distances, proportions, percentages, and more.

It is important to remember that ratios should be simplified when possible, especially if they have common factors. Additionally, a ratio can be equivalent to another ratio if both ratios can be multiplied or divided by the same number to obtain the same value.
