Answer 1

Ответ:

1)

1. 2 3/4

2. 2 2/3

3. 6 13/20

4. 1 5/6

2)

1. 15 1/3 - x = 4 3/5

x = 15 1/3 - 4 3/5

x = 10 11/15

2. x - 2 7/8 = 4 11/12

x = 4 11/12 + 2 7/8

x = 7 19/24

3)

1. ( x - 5 1/12 ) + 7 5/18 = 9 4/9

x - 5 1/12 = 9 4/9 - 7 5/18

x - 5 1/12 = 2 1/6

x = 5 1/12 + 2 1/6

x = 7 1/4

2. 10 4/15 - ( x + 7 1/10 ) = 2 13/30

x + 7 1/10 = 10 4/15 - 2 13/30

x + 7 1/10 = 8 11/30

x = 8 11/30 - 7 1/10

x = 1 4/15
