Answer 2

Răspuns:

a)1/2+x=8/10

Simplific prin 2

1/2+x=4/5

x=4/5-1/2

x=3/10

b)8/5+x=8/10

Simplific prin 2

8/5+x=4/5

x=4/5-8/5

x=-4/5

c) 1/2*x.=4/8

Simplific prin 4

1/2*x=1/2

x=1/2:1/2

x=1

d)x:1/2=1/3

x=2/1x1/3

x=2x1/3

x=1/6

e)x-5/6=8/9

x=8/9+5/6

Amplifica pe prima fracție cu 2,pe a doua fracție cu 3

16/18+15/18=31/18
