Question

What value can be added to 2/15 to make the sum greater than 1/2

Answers: 1/15 , 8/30 , 5/15 , 8/15

Answer 1

2/15+1/15=3/15 which isn't less than a half

2/15+8/30=2/15+4/15=6/15 which isn't less than a half

2/15+5/15=7/15 which isn't less than a half

and 2/15+8/15=10/15 which is greater than a half, and when cancelled down is 2/3 which is definitely greater than a half:)
