Question

Last week, Eva spent 8 and one-eighth hours on homework. This week, she spent eleven and seven-eighths hours. How many more hours did she spend this week?

2 3/4
2 1/4
3 3/4
3 1/4

Answer 1

11 7/8 - 8 1/8

Lets set aside the whole numbers for now.
7/8 - 1/8 = 6/8 reduces to 3/4
Now bring back the whole numbers...
11 - 8 = 3
combine and you get 3 3/4
