What are the ratio and proportion?

The ratio is the division of the two numbers.

Proportion is the relation of a variable with another. It could be direct or inverse.

For example, a/b, where a will be the numerator and b, will be the denominator.

Given that

For 3 cups of raisins  ⇔ 10 cups of trail mix needed

Dividing by 3 to the whole equation

1 cup of raisins ⇔ 10/3 cups of trail mix are needed.

Multiply by 12 to the whole equation

1 × 12 cups of raisins ⇔ (10/3) × 12 cups of trail mix are needed.

12 cups of raisins ⇔ and 40 cups of trail mix are needed.

Hence for 12 cups of raisins, there are 40 cups of trail mix needed.
