Question

efetue as divisões
a)7/8:4/7
b)8/4:6/5
C)25/4:2/5
d)1/2:2/4​

Answer 1

Resposta:

a) $\frac{49}{32}$

b) $\frac{40}{24}$

c) $\frac{125}{8}$

d) $\frac{4}{4}$

Explicação passo-a-passo:

Ex: $\frac{x}{y} : \frac{x}{y} --> \frac{x}{y} . \frac{x}{y} --> \frac{x}{y} = \frac{x}{y}$

a) $\frac{7}{8} : \frac{4}{7} --> \frac{7}{8} . \frac{7}{4} --> \frac{7 . 7}{8 . 4} = \frac{49}{32}$

b) $\frac{8}4} : \frac{6}{5} --> \frac{8}{4} .\frac{5}{6} --> \frac{8.5}{4.6} = \frac{40}{24}$

c) $\frac{25}{4} : \frac{2}{5} --> \frac{25}{4} . \frac{5}{2} --> \frac{25 . 5}{4 . 2} = \frac{125}{8}$

d) $\frac{1}{2} : \frac{2}{4} --> \frac{1}{2} . \frac{4}{2} --> \frac{1 . 4}{2 . 2} = \frac{4}{4}$
