Answer 1

Answer:

12) $\frac{7}{3} = \frac{b}{18}$

$3b = 126$

$\frac{3b}{3} = \frac{126}{3}$

$b = 42$

13) $\frac{3.6}{m} = \frac{1.2}{3.6}$

$1.2m = 12.96$

$\frac{12m}{12} = \frac{12.96}{12}$

$m = 10.8$

14) $\frac{16}{10} = \frac{n + 2}{5}$

$80 = 10n + 20$

$80 - 20 = 10n +20 -20$

$60 = 10n$

$\frac{60}{10} = \frac{10n}{10}$

$n = 6$
