Question

Solve for $x$:

$1.)\frac{2}{3}=\frac{x}{6}$

$2.)\frac{-5}{12}=\frac{15}{x}$

Answer 1

$1.)\frac{2}{3}=\frac{x}{6}$

$\Rightarrow x=\frac{2}{3}\times 6=2\times 2=4$

$\therefore x=4$

$2.)\frac{-5}{12}=\frac{15}{x}$

$\Rightarrow \frac{-1}{12}=\frac{3}{x}$

$\Rightarrow -x=12\times 3=36$

$\therefore x=-36$
