alguém sabe resolver essas questões mínimo múltiplo comum MMC​

Answer 1

Resposta:

4/3 + 1/7

mmc (3,7)= 21

28/21 + 3/21= 31/21

b) 3/8 +1/2

mmc( 8,2)=8

3/8 + 4/8= 11/8

c) 6/5 + 1/3

mmc( 5, 3) = 15

18/15 + 5/15= 23/15

d) 6/4 + 1/5=

mmc( 4,5) = 20

30/20 + 4/20= 34/20

e) 1/3 + 1/2=

mmc( 3,2) = 6

2/6 + 3/6= 5/6

f) 4/3 + 1/5

mmc( 3,5) = 15

20/15 + 3/15= 23/15

g) 9/2 + 2/3=

mmc( 2, 3) =  6

27/6 + 4/6= 31/6

h)  3/7 + 1/6

mmc( 7, 6) = 42

18/42 + 7/42= 25/42

i)  5/9 + 1/3

mmc( 9,3) = 9

5/9 + 3/9= 8/9
