4 1/5 = (4x5 + 1) / 5 = 21/5

3 2/7 = (3x7 + 2) / 7 = 23/7

21 3/8 = (21x8 + 3) / 8 = 171/8

14 5/12 = (14x12 + 5) / 12 = 173/12

125 14/15 = (125x15 + 14) / 15 = 1889/15

b)

1 1/2 = (1x2 + 1) / 2 = 3/2

5 1/10 = (5x10 + 1) / 10 = 51/10

109 9/13 = (109x13 + 9) / 13 = 1426/13

44 4/14 = (44x14 + 4) /14 = 620/14

2 6/18 = (2x18 + 6) /18 = 42/18

405 1/3 = (405x3 + 1) /3 = 1216/3
