Question

Preciso pra segunda frações mistas e as simplifique:
a)19/16 + 2/8
b)14/128 + 19/128
c)16/128 - 3/8
d)268/128 - 1/2

Answer 1

$\rm \: A) \: \frac{19}{16} + \frac{2}{8}$

$\frac{19}{16} + \frac{ \cancel{2}}{ \cancel{8}}$

$\frac{19}{16} + \frac{1}{4}$

$\rm \: \frac{19 + 4}{16}$

$= > \red{ \boxed{ \rm \: \frac{23}{16}}}$

$B) \: \frac{14}{128} + \frac{19}{128}$

$\rm \: \frac{14 + 19}{128}$

$= > \: \red{\boxed{\rm \frac{33}{128}}}$

$\rm \: C) \: \frac{16}{128} - \frac{3}{8}$

$\rm \: \frac{ \cancel{16}}{ \cancel{128}} - \frac{3}{8}$

$\rm \: \frac{1}{8} - \frac{3}{8}$

$\rm \: \frac{1 - 3}{8}$

$\rm \: \frac{ - 2}{8}$

$\rm \: - \frac{2}{8}$ - 1/4
