Answer:

Number of Sugar cups needs for 2 pies = 20/13 cups

Step-by-step explanation:

Given:

Number of Sugar cups used for 5 pies = 6\frac{1}{2} cups = 13/2 cups

Find:

Number of Sugar cups needs for 2 pies

Computation:

Number of Sugar cups needs for 1 pie =  5 / (13/2)

Number of Sugar cups needs for 1 pie = 10 / 13 cups

Number of Sugar cups needs for 2 pies = 2[Number of Sugar cups needs for 1 pie]

Number of Sugar cups needs for 2 pies = 2[10/13]

Number of Sugar cups needs for 2 pies = 20/13 cups
