Answer 1

Ответ:

1) 2 1/4 : 3/8: 1/2 = 9/4 : 3/8 : 1/2 = 12

9/4 : 3/8 = 9/4 * 8/3 = 72/12 = 6

6 : 1/2 = 6 * 2 = 12

2) 2 1/4 : (3/8 : 1/2) = 3

1) 3/8 : 1/2 = 3/8 * 2 = 6/8 =3/4

2) 2 1/4 : 3/4 = 9/4 : 3/4 = 3

3) (6 3/4 - 5 1/8 : 1 9/32) : 2 1/5

1) 5 1/8: 1 9/32 = 41/8 : 41/32 = 41/8 * 32/41 = 4

2) 6 3/4 - 4 = 2 3/4

3) 2 3/4 : 2 1/5 = 11/4 : 11/5 = 11/4 * 5/11 = 5/4 = 1 1/4

4) (3 1/4 + 2 1/6) : 2 3/5 - 2/3 : 4/9 = 7/12

1) 3 1/4 + 2 1/6 = 13/4+13/6 = 39/12 + 26/12 = 65/12

2) 65/12: 2 3/5 = 65/12 : 13/5 = 65/12 * 5/13 = 325/156 = 25/12

3) 2/3 : 4/9 = 2/3 * 9/4 = 18/12

4) 25/12 - 18/12 = 7/12
