b)2/8 ÷ 5/2
c) 4/5 ÷ 7/10​

Answer 1

Resposta:

Explicação passo-a-passo:

a) 1/2÷3/4  => $\frac{1}{2}:\frac{3}{4} => \frac{1}{2}.\frac{4}{3} => \frac{4}{6} => \frac{4:2}{6: 2} => \frac{2}{3}$

b)2/8 ÷ 5/2  => $\frac{2}{8}:\frac{5}{2} => \frac{2}{8}.\frac{2}{5} => \frac{4}{40} => \frac{4:4}{40: 4} => \frac{1}{10}$

c) 4/5 ÷ 7/10​=> $\frac{4}{5}:\frac{7}{10} => \frac{4}{5}.\frac{10}{7} => \frac{40}{35} => \frac{40:5}{35: 5} => \frac{8}{7}$
