Answer 1

Пошаговое объяснение:

№1

1) 2 1/4 * 8 = 9/4 * 8 = 9/1 * 2 = 18/1 = 18

2) 5 1/4 * 3 3/7 = 21/4 * 24/7 = 3/1 * 6/1 = 18/1 = 18

3) 18 : 18 = 1

№2

1) 12 3/8 : 2 1/16 = 99/8 : 33/16 = 99/8 * 16/33 = 3/1 * 2/1 = 6/1 = 6

2) 6 - 5 5/21 = 5 21/21 - 5 5/21 = 16/21

3) 16/21 * 7/8 = 2/3 * 1/1 = 2/3

№3

1) 6 3/4 : 4 1/2 = 27/4 : 9/2 = 27/4 * 2/9 = 3/2 * 1/1 = 3/2 = 1 1/2

2) 1 1/2 + 2 5/7 = 1 7/14 + 2 10/14 = 3 17/14 = 4 3/14

3) 4 3/14 : 8 3/7 = 59/14 : 59/7 = 59/14 * 7/59 = 1/2 * 1/1 = 1/2
