Question

Me ajudem nessa, rapidinho

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

2) $\frac{1}{5} + \frac{1}{4} + \frac{1}{2} =$

Answer 1

Resposta:

Explicação passo a passo:

1)

$mmc(2;3;5)=30$

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

$\frac{20}{30} +\frac{15}{30}+\frac{6}{30} =$

$\frac{41}{30}$

2)

$mmc(2;4;5)=20$

$\frac{1}{5} +\frac{1}{4} +\frac{1}{2} =$

$\frac{4}{20} +\frac{5}{20} +\frac{10}{20} =$

$\frac{19}{20}$
