Question

Kevin has 3 bags of apples weighing a total of 22 1/2 pounds. Two of the bags weigh 6 3/8 pounds and 3 1/4 pounds. How much does the third bag weigh?

A 11 7/8
B 12 4/8
C 12 7/8
D 13 5/8

Answer 1

All bags: 22 1/2 pounds
First bag: 6 3/8 pounds
Second bag: 3 1/4 pounds
Third bag: ???

First of all we need to find the common denominator for all the fractions.

22 1/2 = 22 4/8
3 1/4 = 3 2/8

Now we add both known bags and them substract the result from overall the weight:

6 3/8 + 3 2/8 = 9 5/8
22 4/8 - 9 5/8 = 12 7/8

So the answer is C.

Answer 2

Answer: C -12 7/8

Explanation:

Hi, to answer this question we have to analyze the information given:

• Total weight: 22 1/2 pounds
• Bag 1 = 6 3/8 pounds
• Bag 3 = 3 1/4 pounds

First, we have to sum the weights of bag 1 and 2:

6 3/8 + 3 1/4=

6 3/8 + 3 2/8 = 9 5/8

Finally we subtract the number calculated to the total weight.

22 1/2 - 9 5/8=

22 4/8 -9 5/8=

21 (8/8 +4/8) - 9 5/8 =

21 12/8 - 9 5/8=

12 7/8

3rd bag weight: 12 7/8 pounds
