2)m=2/115

3)y=4 1/2

4)y=4 8/9

5)a=1 2/5

6)z=9 1/6

Пошаговое объяснение:

1)2/7×x=2 2/7

x=2 2/7÷2/7

x=8

2)14+3/8×m=1/4

m=1/4÷14 3/8

m=2/115

3)3/5×y=2 9/10-1/5

y=(2 9/10-1/5)÷3/5

y=4 1/2

4)y-2/9=4 2/3

y=4 2/3+2/9

y=4 8/9

5)3/7×a+2/5=1

1-2/5=0,6 (6/10)

a=6/10÷3/7

a=1 2/5

4 1/3-2/3=3 2/3

z=3 2/3÷2/5

z=9 1/6
