Question

resolva as frações, simplificando quando necessário

Answer 1

A) 1/2+3/5=5+6/10=R:11/10
MMC(2,5)=10

B)2/7+3/2=4+21/14=R:25/14
MMC (7,2)=14

C)1/3+1/2=2+3/6=5/6
MMC (3,2)=6
Espero ter ajudado

Answer 2

a)
$\frac{1}{2} + \frac{3}{5} = \frac{5+6}{10} = \frac{11}{10}$

b)
$\frac{2}{7} + \frac{3}{2} = \frac{4+21}{14} = \frac{25}{14}$

c)
$\frac{1}{3} + \frac{1}{2}= \frac{2+3}{6} = \frac{5}{6}$
