Решите уравнения с дробями
1/8+x=3/5
4/5-b=1/6
d+1/3=5/12
y-2/9=7/18
3/8-z=2/9
4/15+m=5/12

Answer 1

1/3-(1/9+1/6)=1/3-(4/36+6/36)=1/3-10/36=12/36-10/36=2/36=1/12
(2/3+1/9)-13/18=(6/9+1/9)-13/18=7/9-13/18=14/18-13/18=1/18
3/4-1/2+7/8=6/8-4/8+7/8=9/8

1/8+x=3/5
x=3/5-1/8
x=27/40-5/40
x=22/40
x=11/20

Answer 2

1/3-(1/9+1/6)=1/3-(4/36+6/36)=1/3-10/36=12/36-10/36=2/36=1/12
(2/3+1/9)-13/18=(6/9+1/9)-13/18=7/9-13/18=14/18-13/18=1/18
3/4-1/2+7/8=6/8-4/8+7/8=9/8
