Answer 1

3/7 * 14/20 = 3/10

1 1/3 * 2/3 = 4/3 * 2/3 = 8/9

2 2/7 * 1 1/16 = 16/7 * 17/16 = 17/7 = 2 3/7

5 1/2 - 1 1/4 = 11/2 - 5/4 = 22/4 - 5 /4 = 17/4 = 4,25

6 7/10 * 4 2/20 = 67/10 * 82/20 = 2747/100 = 27,47

4/5 : 2/10 = 4/5 * 10/2 = 4

2/7 : 2/14 = 2/7 * 14/2 = 2

1 1/2 : 2/3 = 3/2 : 2/3 = 3/2 * 3/2 = 9/4 = 2,25

4 1/5 : 2 1/21 = 20/5 : 42/21 = 20/5 * 21/42 = 2

6 2/8 : 1 1/4 = 50/8 : 5/4 = 50/8 * 4/5 = 10/2 = 5

5 6/7 : 2/14 = 41/7 : 2/14 = 41/7 * 14/2 = 41

3 3/9 : 2 2/18 = 30/9 : 38/18 = 30/9 * 18/38 = 30/19 = 1 11/19
