Multiply fractions by multiplying the numerators and multiplying the denominators. For eg; $\frac{2}{3}$ * $\frac{1}{5}$ Now multiply numerators i.e. 2 * 1 = 2 and denominators =3 * 5 = 15 The multiplication result is $\frac{2}{15}$ Divide two fractions by using the reciprocal of the divisor (the second fraction) and then changing division to multiplication. For example : $\frac{5}{4}$ $\div$ $\frac{15}{4}$ = $\frac{5}{4}$ $\times$ $\frac{4}{15}$ = $\frac{1}{3}$
