2-101.

Multiply the mixed numbers.

Convert the mixed numbers to fractions greater than one before multiplying.

1. $1\frac{1}{3}\cdot1\frac{1}{2}$

Multiply the whole number by a Giant One so that it has the same denominator as its fraction.

For an example, see part (c).

1. $3\frac{1}{3}\cdot2\frac{1}{2}$

Multiply two fractions together by writing the product of their numerators over the product of their denominators.

For an example, see part (c).

1. $2\frac{1}{2}\cdot2\frac{1}{2}$

$\left(2\cdot\frac{2}{2}+\frac{1}{2}\right)\cdot\left(2\cdot\frac{2}{2}+\frac{1}{2}\right)$

$\left(\frac{4}{2}+\frac{1}{2}\right)\cdot\left(\frac{4}{2}+\frac{1}{2}\right)$

$\frac{5}{5}\cdot\frac{5}{2}=\frac{25}{4}=6\frac{1}{4}$

1. $2\frac{1}{2}\cdot1\frac{1}{4}$

$\frac{25}{8}=3\frac{1}{8}$
