Question

calcule e simplifique o resultado se possivel
1/3+2/9+4/3=.......
7/15+3/15-1/10=.....

Answer 1

1/3 + 2/9 + 4/3
MMC de 3 e 9 = 9
1/3/3 + 2/9/1 + 4/3/3
3/9  + 2/9 + 12/9 = 17/3(não dá pra simplificar)

7/15 + 3/15 - 1/10
MMC de 10 e 15 = 30
7/15/2 + 3/15/2 - 1/10/3
14/30 + 6/30 - 3/30
17/30
