Question

Sam and Lou need a total of 1 foot of a wire for a science project. Sam’s wire measured 8/12-foot long. Lou’s measured 7/8 foot long.Do they have enough wire for the science project?

Answer 1

Explanation:

So 8/12 + 7/8 needs to be greater than 1 foot? It is.

8/12 = 2/3

7/8 + 2/3 =

7/8 = 3*7 / 8*3 = 21 / 24

2/3 = 8*2 /8*3 = 16 / 24

Now add them

21 / 24 + 16/24 = 37/24 which is way more than 1 foot.

37/24 = 1 13/24
