Answer 1

Resposta:

A) 2/6 = 9/x

$\frac{2}{6} = \frac{9}{x} \\ \\ 2x = 54 \div (2) \\ x = 27$

B) 1/3 = y/12

$\frac{1}{3} = \frac{y}{12} \\ \\ 3y = 12 \div (3) \\ x = 4$

C) z/10 = 6/5

$\frac{z}{10} = \frac{6}{5} \\ \\ 5z = 60 \div (5) \\ z = 12$

D) 8/t = 2/15

$\frac{8}{t} = \frac{2}{15} \\ \\ 2t = 120 \div (2) \\ t = 60$
