Simplify

a. 3/8 - 1/4 g. 0.2 - 1/10

b. 5/9 + 1/3

c.-1/2 + 1/4

e. 10 - 1/2

f. 1/9 + 1/6

A. 1/4=2/8 so 3/8-2/8=1/8

b. 1/3=3/9 so 5/9+3/9=8/9

c. - 1/2=-2/4 so - 2/4+1/4=-1/4

e. 10=20/2 so 20/2-1/2=19/2

f. 1/9=2/18 and 1/6=3/18 so 2/18+3/18=5/18

g. 0.2=2/10 so 2/10-1/10=1/10

A. 1/4=2/8 that's why ⇒ 3/8-2/8=1/8

g. 0.2=2/10 that's why ⇒ 2/10-1/10=1/10=0.1

b. 1/3=3/9 that's why ⇒ 5/9+3/9=8/9

c. - 1/2=-2/4 that's why ⇒ - 2/4+1/4=-1/4

e. 10=20/2 that's why ⇒ 20/2-1/2=19/2=18 1/2

f. 1/9=2/18 and 1/6=3/18 that's why ⇒ 2/18+3/18=5/18
