Помогите пж

Answer 1

Упростить:

( 3+ 1/3/4) + ( 2+ 1/15/4) – ( 1+ 1/5/3)

Выселение:

1) ( 3+ 4/3) + ( 2+ 4/15) – ( 1+ 3/5)

2) 13/3 + 34/15 – 8/5 = 5

Answer 2

Ответ:

5

Пошаговое объяснение:

1) 5/12 + 1/3 = 5/12 + 4/12 = 9/12 = 3/4

2) 1 : 3/4 = 1 * 4/3 = 4/3 = 1 1/3

3) 3 + 1 1/3 = 4 1/3

4) 3 + 3/4 = 3 3/4

5) 1 : 3 3/4 = 1 : 15/4 = 1 * 4/15 = 4/15

6) 2 + 4/15 = 2 4/15

7) 1 + 2/3 = 1 2/3

8) 1 : 1 2/3 = 1 : 5/3 = 1 * 3/5 = 3/5

9) 1 + 3/5 = 1 3/5

10) 4 1/3 + 2 4/15 = 4 5/15 + 2 4/15 = 6 9/15 = 6 3/5

11) 6 3/5 - 1 3/5 = 5
