Question

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

Answer 1

Answer:

The weight of bag of grapefruit  =$3\frac{27}{100}$ pounds

Step-by-step explanation:

The total weight of apples purchased   = 1  5/8 pounds

Now, $1\frac{5}{8} = 1+ \frac{5}{8} = 1 + 0.625 =1.625$

So, the weight of apples brought = 1.625 pounds.

The total weight of bananas purchased   = 2  3/16 pounds

Now, $12\frac{3}{16} = 2+ \frac{3}{16} = 2+ 0.1875 =2.1875$

So, the weight of bananas brought = 2.1875 pounds.

Let us assume the total weight of grapefruit weight = m pounds

Now, total weight = 7   1/12 pounds =  7.0833

⇒ Weight of ( Apples + Banana + Grapefruit) = Total Weight

⇒1.625 pounds +  2.1875 pounds + m = 7.0833 pounds

or, m  =  7.0833 - 3.8125 = 3 .27

or, m = 3.27

Now, $3.27 = 3 + 0.27 = 3 + \frac{27}{100} = 3\frac{27}{100}$

Hence. the weight of bag of grapefruit  =$3\frac{27}{100}$
