What is ratio?

A comparison of two or more values or quantities that are related to one another is known as a ratio in mathematics.

It shows the relative size or proportion of the values being compared and is expressed as the quotient of one quantity divided by the other.

A colon (:) or a fraction can be used to represent ratios between values.

If 2 cups of flour make 4 pancakes, then we can assume that 6 cups of flour would make 12 pancakes.

To determine the amount of baking powder required, we can use the ratio of 1 tablespoon of baking powder per 2 cups of flour.

If 2 cups of flour require 1 tablespoon of baking powder, then 6 cups of flour would require:

(6 cups flour) x (1 tablespoon baking powder / 2 cups flour) = 3 tablespoons of baking powder

Therefore, we would require three tablespoons of baking powder to make twelve pancakes.

Therefore, A is the answer.
