Answer 1

Ответ:

4 13/15; 4 4/7; 6; 22/33; 1 1/5

Пошаговое объяснение:

1) 4 4/15 + 3/5 = 4 4/15 + 9/15 = 4 13/15

2) 5 - 3/7 = 4 7/7 - 3/7 = 4 4/7

3) 1 1/4 * 4 4/5 = 5/4 * 24/5 = (5 * 24)/(4 * 5) = 24/4 = 6

4) 22 * 1/33 = 22/33

5) 4 1/2 * 4/15 = 9/2 * 4/15 = (9 * 4)/(2 * 15) = (3 * 2)/(1 * 5) = 6/5 = 1 1/5
