7-74.

Simplify each of the following expressions by using one of the strategies in the Math Notes box for this lesson.

1. $\frac { 2 } { 3 } \div \frac { 3 } { 5 }$

Write the problem as multiplication by taking the reciprocal of the second fraction:$\frac{2}{3} \cdot \frac{5}{3}$

Multiply the numerators and the denominators: $\frac{10}{9}$

1. $\frac { 5 } { 6 } \div \frac { 1 } { 12 }$

Follow the steps you used to solve part (a).

$10$

1. $3 \frac { 1 } { 8 } \div 2 \frac { 1 } { 2 }$

Write both mixed numbers as fractions greater than one, then follow the examples in part (a) and part (b).
