Выполните действия (1-3): 1) 33:23 - 23: - 1. 1) 3 2 3) 101/6/2 : 8/12 + 1/²/3 ; 17 11​

Answer 1

Пошаговое объяснение:

№1

1) 3 1/9 : 2 1/3 = 28/9 : 7/3 = 28/9 * 3/7 = 4/3 * 1/1 = 4/3 = 1 1/3

2) 1 1/3 - 2 5/6 = 1 2/6 - 2 5/6 = -1 3/6 = -1 1/2

№2

1) 4 3/13 : 1 19/26 = 55/13 : 45/26 = 55/13 * 26/45 = 11/1 * 2/9 = 22/9 = 2 4/9

2) 1 5/7 - 2 4/9 = 1 45/63 - 2 28/63 = 1 45/63 - 1 91/63 = 46/63

№3

1) 10 16/17 : 8 5/11 = 186/17 : 93/11 = 186/17 * 11/93 = 2/17 * 11/1 = 22/17 = 1 5/17

2) 1 5/17 + 1 2/3 = 1 15/51 + 1 34/51 = 2 49/51
