Question

Calcule as operações com frações

A)7/13 + 2/13
B)8/15 - 2/15
C)9/11 + 10/11
D)10/3 - 7/3
E)13/10 + 29/10
F)31/6 - 17/6
G)5/4 + 2/4
H)11/6 + 1/6 + 5/6

Answer 1

a)
$\frac{7}{13} + \frac{2}{13} = \frac{9}{13}$
b)
$\frac{8}{15} - \frac{2}{15} = \frac{6}{15}$
c)
$\frac{9}{11} + \frac{10}{11} = \frac{19}{11}$
d)
$\frac{10}{3} - \frac{7}{3} = \frac{3}{3}$
e)
$\frac{13}{10} + \frac{29}{10} = \frac{42}{10}$
f)
$\frac{31}{6} - \frac{17}{6} = \frac{14}{6}$
g)
$\frac{5}{4} + \frac{2}{4} = \frac{7}{4}$
h)
$\frac{11}{6} + \frac{1}{6} + \frac{5}{6} = \frac{17}{6}$
