Answer 1

Ответ:

Пошаговое объяснение:

1) (3 1/6-5 1/6:4 2/15):30 3/5 = 1/16

1) 5 1/6 : 4 2/15 = 31/6 : 62/15 = 31/6 * 15/62 =  5/4 = 1 1/4

2) 3 1/6 - 1 1/4 = 3 2/12 - 1 3/12 = 2 14/12 - 1 3/12 = 1  11/12

3) 1 11/12 : 30 2/3 = 23/12 : 92/3 = 23/12 * 3/92 = 1/16

2) (2 12/35:4/5-1 8/35)×3 1/3​=51\100

1) 2 12/35:4/5=82\35*5\4=41\14=2 13\14

2) 2 13\14-1 8\35=2 65\70-1 16\70=1 7\10

3) 1 7\10*3 1\3=17\10*10/3=17/3=5 2/3
