Answer 1

Resposta:

as contas são frações????????

Answer 2

a) 1/2 +2/3

mmc: 6

3+4/6= 7/6

b) 3/8 + 13/8

3+13= 16

16/8= 2/1

c)1/8+3/6

mmc= 24

3+4 /24= 7/24

d)1/4+2+7

mmc =4

1+8+24/4 = 37/4

e) 1/4+3/7-1/3

mmc =84

=29/84

f)2/3+1/5

mmc =15

10+3/15 = 13/15

g) 7/3 - 2-5

mmc = 3

7-6-15 / 3 = -14/3
