Answer 1

a) x + 4/5 = 1 1/2

    x + 8/10 =  1 5/10

x = 7/10

 

b)

x - 4/5 = 1 1/2

x - 8/10 = 1 5/10

x= 2 3/10

 

c)

5 4/9 + x = 7 1/2

5 8/18 + x = 7 9/18

x= 2 1/18

 

d)

x-2 3/4=5 6/7

x-2 21/28=5 24/28

x=8 17/28

 

e)

8 1/12 - x = 5 1/4

8 1/12 - x = 5 3/12

-x = -2 10/24

x = 2 10/24

 

f)

6 3/7 - x = 2 1/2

6 6/14 - x = 2 7/14

-x = -3 13/14

x=3 13/14
