Question

Calcule as somas e simplifiique se possivel:

2\9 + 6\9=

7\6+ 5\3=

1+ 3\5=

3\2+ 7\9

Answer 1

2/9 +6/9= 8/9

7/6+5/3 =
7/6+ 10/6 =17/6

1+3/5=
5/5+3/5= 8/5

3/2 + 7/9 =
27/18 + 14/18 = 41/18

Answer 2

1)

$\frac{2}{9} + \frac{6}{9}= \frac{8}{9}$

2)

$\frac{7}{6}+ \frac{5}{3}$

mmc(6,3)=6


$\frac{7+10}{6} = \frac{17}{6}$

3)

$1+ \frac{3}{5}$

$\frac{5+3}{5}= \frac{8}5}$

4)

$\frac{3}{7} + \frac{7}{9}$

mmc(2,9)=18

$\frac{27+14}{18}= \frac{41}{18}$
