1)5 3/16-2 1/48=
2)12 4/21-7 3/14=
3) 4 3/8-1 5/24+2 3/16=
4)8 1/3+2 7/18-3 8/9=

Answer 1

1)5 3/16-2 1/48= 5 9/48 - 2 1/48 = 3 8/48 = 3 1/6

2)12 4/21-7 3/14= 12 8/42 - 7 9/42 = 512/42 - 303/42 = 209/42 = 4 41/42

3) 4 3/8-1 5/24+2 3/16= 4 18/48 - 1 10/48 + 2 9/48 = 3 8/48 + 2 9/48 = 5 17/48

4)8 1/3+2 7/18-3 8/9= 8 6/18 + 2 7/18 - 3 16\18 = 10 13/18 - 3 16/18 = 9 31/18 -

- 3 16/18 = 6 15/18 = 6 5/6
