First day: 3/8
Second day: 1 1/8
Third day: 1 1/2
Fourth day: ?
Fifth day: ?
Find the difference:
3/8 ------ 8/8 -------- 1 1/8 = 6/8 = 3/4
3/4------ 4/4 ------- 1 2/4 = 3/4
The difference is 3/4.
Add 3/4 to the third day to find 4th and add 4th to find 5th.
4th day: 1 1/2 + 3/4
1 2/4 + 3/4
6/4 + 3/4 = 9/4 = 2 1/4
5th day: 2 1/4 + 3/4
9/4 + 3/4
12/4 = 3
