Multiplying and Dividing Rational Numbers

A rational number is any number that can be expressed as the quotient or fraction of two integers, where the denominator is not zero.

To divide two fractions, multiply the first fraction by the reciprocal of the second fraction.

The reciprocal of a fraction $$\frac{a}{b}$$ is $$\frac{b}{a}$$ .

To multiply fractions, multiply the numerators together and the denominators together.

To simplify a fraction means to reduce it to its lowest terms, where the numerator and denominator have no common factors other than 1.

$$\frac{-2}{25}$$ .

$$\frac{3}{32}$$ .

$$1$$ .

$$-15 \frac{3}{8}$$ .

Multiply the whole number by the denominator, add the numerator, and place the result over the original denominator.
