Question

If you used 4/7 of an item on Wednesday and 1/4 on Thursday, how much would you have left from the whole amount on Friday?

Answer 1

Answer: 5/28 left over.

Explanation:

Make both of the fractions have the same denominator:

4/7 x 4/4 = 16/28

1/4 x 7/7 = 7/28

Combine:

16/28 + 7/28 = 23/28

So on Friday you have 5/28 of the item left over.

Answer 2

5/28

Explanation:

So first find a common denominator

4/7 + 1/4 can be translated as 16/28+7/28

16/28+7/28=23/28

NOw we have to subtract 23/28 from1, or 28/28, and that is 5/28
