Advice

To add two fractions, they must be expressed with a common denominator.

For example, if you have $\frac{1}{3}+\frac{2}{11}$ , the common denominator would be $33$ , from $(3 * 11)$ .

$\frac{11+6}{33}$

$\frac{17}{33}$

Similarly, to subtract two fractions, express them with a common denominator.

$\frac{1}{3}-\frac{2}{11}$

$=\frac{11-6}{33}$

$=\frac{5}{33}$

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

$\frac{1}{3} \times\frac{2}{11}$

$=\frac{1\times 2}{3\times11}$

$=\frac{2}{33}$

To divide two fractions, flip the second fraction upside down and then follow the steps to multiply.

$\frac{1}{3} \div \frac{2}{11}$

$=\frac{1}{3} \times \frac{11}{2}$

$=\frac{1\times11}{3\times2}$

$=\frac{11}{6}$
