Respuesta :

Answer: 3 1/2 + 4 3/4 = x +  1 3/8

There was 6 7/8 pounds of fruit in the salad.

Step-by-step explanation:

Hi to answer this question we have to write an equation:

She bought 3 1/2 pounds of oranges and 4 and 3/4 pounds of peaches. Adding both quantities is equal to the amount of fruit used in the salad (x) plus the amount of fruit left.

Mathematically speaking:

3 1/2 + 4 3/4 = x + 1 3/8  

Solving for x:

3 2/4 + 4 3/4 = x+ 1 3/8

7 5/4 =x + 1 3/8

7 5/4 - 1 3/8 =x

7 10/8- 1 3/8 =x

6 7/8 =x
