Question

Adição 2/3 3/5 1/15.

Answer 1

Resposta:

$\frac{4}{3}=1\frac{1}{3}=1,333...$

Explicação:

$\frac{2}{3}+ \frac{3}{5}+ \frac{1}{15}$

$\frac{2*5}{3*5}+ \frac{3*3}{5*3}+ \frac{1*1}{15*1}$

$\frac{10}{15}+ \frac{9}{15}+ \frac{1}{15}$

$\frac{10+9+1}{15}$

$\frac{20}{15}=\frac{4}{3}=1\frac{1}{3}=1,333...$
