В решении.

Пошаговое объяснение:

По действиям:

1) 3 3/4 * 3/4 = 15/4 * 3/4 = (15 * 3)/16 = 45/16;

2) 8 4/9 : 3 4/5 = 76/9 : 19/5 = (76 * 5)/(9 * 19) = 20/9;

3) 1 1/2 : 27 = 3/2 : 27 = 3/(2 * 27) = 1/18;

4) 45/16 - 20/9 + 1/18 = (9*45 - 16*20 + 8*1)/144 =

= (405 - 320 + 8)/144 = 93/144 = 31/48;

5) 31/48 : 1 29/48 = 31/48 : 77/48 = (31 * 48)/(48 * 77) = 31/77. Ответ.

Answer 2

Ответ:

31/77

Пошаговое объяснение:

1) 3. 3/4 * 3/4 = 15/4 * 3/4 = 45/16 = 2. 13/16

2) 8. 4/9 : 3. 4/5 = 76/9 : 19/5 = 76/9 * 5/19 = 4/9 * 5/1 = 20/9 = 2. 2/9

3) 1. 1/2 : 27 = 3/2 : 27 = 3/2 * 1/27 = 1/2 * 1/9 = 1/18

4) 2. 13/16 - 2. 2/9 = 2. 117/144 - 2. 32/144 = 85/144

5) 85/144 + 1/18 = 85/144 + 8/144 = 93/144 = 31/48

6) 31/48 : 1. 29/48 = 31/48 : 77/48 = 31/48 * 48/77 = 31/77
