Question

2- Calcule as somas abaixo, simplificando o resultado sempre que possível.
a) 3/2 + 2/3
b) 1/3 + 4/6
c) 3/4 + 5/6
d) 1/2 + 1/3 + 1/5​

Answer 1

Explicação passo-a-passo:

a)

$\frac{3}{2}+\frac{2}{3}=\frac{3.3+2.2}{6}=\frac{9+4}{6}=\frac{13}{6}$

b)

$\frac{1}{3}+\frac{4}{6}=\frac{2.1+1.4}{6}=\frac{2+4}{6}=\frac{6}{6}=1$

c)

$\frac{3}{4}+\frac{5}{6}=\frac{3.3+2.5}{12}=\frac{9+10}{12}=\frac{19}{12}$

$\frac{1}{2}+\frac{1}{3}+\frac{1}{5}=\frac{15.1+10.1+6.1}{30}=\frac{15+10+6}{30}=\frac{31}{30}$
