EG1) 7/8 + 3/4 = 13/8 = 1 5/8
13/ 8 = Improper Fraction
8 goes into 13 once with 5 left over
1 5/8 = Mixed Fraction
EG2) 2 1/5 - 3/4
2 x 5 = 10
10 + 1 = 11
11/5 - 3/4
11 x 4 = 44
5 x 4 = 20
3 x 5 = 15
4 x 5 = 20
44/ 20 - 15/20 = 29/ 20 = 1 9/20
EG3) 5 1/3 - 2 4/5 =
3 x 5 = 15
15 + 1 = 16
16/3
2 x 5 = 10
10 + 4 = 14
14 / 5
16/3 - 14/5
16 x 5 = 80
3 x 5 = 15
14 x 3 = 42
5 x 3 = 15
80/ 15 - 42/ 15 = 38/15
38/ 15 = 2 8/15
