Question

Last week, Carlos had completed 5/8 of The World of Math. This week, he worked hard earning energy points, and now he has completed 7/8 of The World of Math. What fraction of The World of Math did Carlos complete this week?

Answer 1

It would be 1 4/8 because 5 plus 7 equals 12.And 12 divided by 8 equals 1 remainder of 4.So, it would be 1 4/8

Answer 2

2/8. Because 5-7= 2. And you always keep the dominator if both dominators are the same number.
