Solve each equation below for $x$ . Then check your solutions.

$\frac{x}{8\ }=\frac{3}{4}$
Hint (a):
Multiply both sides by $8$ .
$8\cdot\frac{\textit{x}}{8}=\frac{3}{4}\cdot8$
$x=\frac{24}{4}$
Answer (a):
$x=6$

$\frac{2}{5}=\frac{x}{40}$
Hint (b):
What can you multiply both sides of the equation by to eliminate the denominators?

$\frac{1}{8}=\ \frac{x}{12}$
Answer (c):
$x=1.5$

$\frac{x}{10}=\frac{12}{15}$
Hint (d):
Use the method from part (a)
