calcule as frações:

⅜ + + ¼ =
⅔ × × ⅝ =
⅜ / ⅔ =​

Answer 1

Resposta:

1) $\frac{5}{8}$

2) $\frac{5}{12}$

3) $\frac{9}{16}$

Explicação passo a passo:

1) $\frac{3}{8} + \frac{1}{4} \\\\\= \frac{3+2}{8} \\\\= \frac{5}{8}$

2)$\frac{2}{3} * \frac{5}{8} \\\\= \frac{10}{24} ... simplificando...\\\\= \frac{5}{12}$

3)$\frac{3}{8} dividido por \frac{2}{3}\\ ... inverte a segunda fracao e multiplica\\\\= \frac{3}{8} *\frac{3}{2}\\= \frac{9}{16}$
