Answer 2

Answer:

Option B is the right answer.

In mathematics, a ratio is the relationship between two numbers that indicate how many times the first number contains the second number.

For example, if there is a bowl of 3 apples and 2 oranges, the ratio of apples to oranges would be 3:2.

It is used to solve many problems of mathematics and there can be complex ratios involving more than two numbers as well.
