1) with 3/5 as a fraction one whole number can be written as 5/5
so you could rewrite 4 as 3 and 5/5 now subtract 3/5 and you are left with
3 and 2/5
2) one whole number can be written as 7/7
Now you have 4 and 7/7 minus 4/7 to get 4 and 3/7
Using the same steps for the rest:
3) 5 and 3/3 -2/3 = 5 and 1/3
4) 4 and 8/8 - 7/8 = 4 and 1/8
5) 6 and 5/5 - 2/5 = 6 and 3/5
