Question

Lynne bought a bag of grapefruit, 1 and 5/8 pounds of apples, and 2 and 3/16 pounds of bananas. The total weight of her purchases was 7 and 1/2 pounds. How much did the bag of grapefruit weigh?

Answer 1

Let, the weight of Grapefruit = x
It would be: x + 1 5/8 + 2 3/16 = 7 1/2
x + 13/8 + 35/16 = 15/2
16x+26+35 /16 = 15/2
16x+61/16 = 15/2
2(16x+61) = 15*16
32x + 122 = 240
x = 118/32
x = 3.68
x = 3 11/18 Pound

In short, Your Answer would be 3 11/18 Pound

Hope this helps!

Answer 2

The answer would be 3 and 11/16.
First add the 1 and 5/8 to 2 and 3/16.
Subtract this sum from the total 7 1/2 pounds. This will give the weight of grapefruit.
