Chapter 6: Ratio, Proportion, and Probability

Solve the equation.

$-\frac{3}{8}x-5=7$

Use equivalent ratios to solve the proportion.

$\frac{b}{14}=\frac{27}{42}$

Solve the equation.

$\frac{1}{4}x-\frac{3}{8}=9$

Tell whether the ratio is in simplest form. If not, write it in simplest form. Then write the ratio in two other ways.

$\frac{15}{3}$

Use equivalent ratios to solve the proportion.

$\frac{14}{3}=\frac{a}{15}$

Tell whether the ratio is in simplest form. If not, write it in simplest form. Then write the ratio in two other ways.

$\frac{50}{6}$

Solve the equation.

$\frac{3}{5}x-\frac{2}{5}=2$

Use equivalent ratios to solve the proportion.

$\frac{11}{9}=\frac{y}{81}$

Tell whether the ratio is in simplest form. If not, write it in simplest form. Then write the ratio in two other ways.

$63:18$

Tell whether the ratio is in simplest form. If not, write it in simplest form. Then write the ratio in two other ways.

$24:8$
