A resume calls for 3 cups of flower and 2 cups of sugar. Marty only has 2.5 cups of flower. To keep the recipe proportional, how much sugar should he use?

He should use 5/3 cups of sugar

Step-by-step explanation:

In this question, we are asked to give the amount of sugar to be used in a flower-sugar recipe to leave the ratio of flower and sugar in the recipe as 3 cups of flower to 2 cups of sugar.

To answer this question, we first identify the ratio at which the flour and the sugar are present. This is given in the question to be 3:2

Now, Marty has only 2.5 cups of flour, so what we need to do is find the amount if sugar needed to keep this ratio constant.

Let’s do this;

3:2 = 2.5:s

Now s represents the number of cups of sugar.

3/2 = 2.5/s

3s = 2 * 2.5

3s = 5

s = 5/3 cups of sugar
