1) (1/4)² = 1/16

2) (1/9)³ = 1/729

3) (2/5)³ = 8/125

4) (4/7)³ = 64/343

5) (1 1/2)² = (3/2)² = 9/4 = 2 1/4

6) (1 1/6)² = (7/6)² = 49/36 = 1 13/36

7) (2 1/3)³ = ( 7/3)³ = 343/81 = 4 19/81

8) (3 1/2)³ = (7/2)³ = 343/8 = 42 7/8

1) (2/7 + 3 1/2) * 4 2/3 = 17 2/3

1) 2/7 +3 1/2 = 4/14 + 3 7/14 = 3 11/14

2) 3 11/14 * 4 2/3 = 53/14 * 14/3 = 53/3 = 17 2/3

2) (4 1/5 - 2 3/4) * 2 2/19 = 3 1/19

1) 4 1/5 - 2 3/4 = 4 4/20 - 2 15/20 = 3 24/20 - 2 15/20 = 1 9/20

2) 1 9/20 * 2 2/19 = 29/20 * 40/19 = 58/19 = 3 1/19

3) (5 6/7 + 3 5/21) * 2 1/10 = 19 1/10

1) 5 6/7 + 3 5/21 = 5 18/21 + 3 5/21 = 8 23/21 = 9 2/21

2) 9 2/21 * 2 1/10 = 191/21 * 21/10 = 191/10 = 19 1/10

4) (7 5/12 - 3 1/6) * 2 2/17 = 9

1) 7 5/12 - 3 1/6 = 7 5/12 - 3 2/12 = 4 3/12 = 4 1/4

2) 4 1/4 * 2 2/17 = 17/4 * 36/17 = 9
