​

Answer 1

Resposta:

A) 5/3

B)1

C)3

D)50/9

Explicação passo-a-passo:

$A) \frac{2}{3} /\frac{2}{5} = \frac{2}{3} * \frac{5}{2} = \frac{2.5}{3.2} = \frac{10}{6} = \frac{5}{3} \\B) \frac{1}{9} /\frac{4}{36} = \frac{1}{9} * \frac{36}{4} = \frac{1*36}{9.4} = \frac{36}{36} = 1\\C) \frac{17}{13} /\frac{51}{117} = \frac{17}{13} * \frac{117}{51} = \frac{17.117}{13.51} = \frac{1989}{663} = \frac{663}{221} = 3\\D)\frac{2}{15} /\frac{3}{125} = \frac{2}{15} * \frac{125}{3} = \frac{2.125}{15.3} = \frac{250}{45} = \frac{50}{9}$
