Question

Box A weights 1 7/10 pounds. Box B weighs 1/4 pouns less than Box A what is the total weight of the two boxes?

Answer 1

If I divide the weights of 17/10 I will get 1.7.
And if I divide the pound of 1/4 I will get 0.25

Answer 2

1 7/10 - 1/4 =

1 14/20 - 5/20 = 1 9/20

1 14/20 + 1 9/20 = 2 23/20

2 23/20 = 3 3/20

3 3/20 pounds is the total weight of the two boxes.
