Question

Faça os cálculos e se possível simplifique

a)1/5+3/5+4/5
b)7/6-1/2
c)9/3-2/6
d)2/9+4/3
e)1/6+1/8
f)1/3-1/6

Answer 1

a)

$\frac{1}{5} + \frac{3}{5} + \frac{4}{5} = \frac{1 + 3 + 4}{5} = \frac{8}{5}$

b)

$\frac{7}{6} - \frac{1}{2} = \frac{7 - 3}{6} = \frac{4}{6} = \frac{2}{3}$

c)

$\frac{9}{3} - \frac{2}{6} = \frac{18 - 2}{6} = \frac{16}{6} = \frac{8}{3}$

d)

$\frac{2}{9} + \frac{4}{3} = \frac{2 + 12}{9} = \frac{14}{9}$

e)

$\frac{1}{6} + \frac{1}{8} = \frac{4 + 7}{24} = \frac{11}{24}$

f)

$\frac{1}{3} - \frac{1}{6} = \frac{2 - 1}{6} = \frac{1}{6}$
