Question

Calcule e simplifique os resultados quanto for possível:
a. 1/2 - 1/3=
b. 5/6 - 1/3=
c. 4/5 - 2/7=
d. 7/8 - 1/6=
e. 5/4 - 1/2=
f. 8/ 10 - 1/ 5=

Answer 1

OI....

a) 1/2 - 1/3 = 0 mmc = 6

3 - 2/6

1/6

b) 5/6 - 1/3 = o mmc = 6

5 - 2/6

3/6 ÷ 3

1/2

c) 4/5 - 2/7 = o mmc =35

28 - 10/35

18/35

d) 7/8 - 1/6 = o mmc = 24

21 - 4/24

17/24

e) 5/4 - 1/2 = o mmc = 4

5 - 2/4

3/4

f) 8/10 - 1/5

4/5 - 1/5 = o mmc = 5

4 - 1/5

3/5
