Me ajudem!

Answer 1

Olá
a) 1/2 - 1/3 = mmc de 2,3=6
3/6 - 2/6
1/6

b) 5/6 - 1/3 = mmc de 6,3 = 6
 5/6 - 2/6
3/6 ÷ 3
1/2

c) 4/5 - 2/7 =mmc de 5,7 =35
28/35 - 10/35
18/35

d) 7/8 - 1/6 = mmc de 8,6=24
21/24 - 4/24
17/24

e) 5/4 - 1/2 = mmc de 4,2 = 4
5/4 - 2/4
3/4

f)8/10 - 1/5=mmc de 10,5=10
8/10 - 2/10
6/10 ÷ 2
3/5

Bons estudos.
