Answer:
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
