Answer 1

oi!!

1. a)

$\frac{3}{6} + \frac{2}{6} = \frac{5}{6}$

b)

$\frac{13}{7} + \frac{1}{7} = \frac{14}{7}$

c)

$\frac{2}{7} + \frac{1}{7} + \frac{5}{7} = \frac{8}{7}$

d)

$\frac{4}{10} + \frac{1}{10} + \frac{3}{10} = \frac{8}{10}$

2. a)

$\frac{5}{4} - \frac{1}{2} = \frac{3}{4}$

espero ter ajudado!! :)
