Solution

16 \div \frac{4}{5}

20

Solution steps

16 \div \frac{4}{5}

Convert element to fraction:

16 = \frac{16}{1}

= \frac{16}{1} \div \frac{4}{5}

Apply the fraction rule:

\frac{a}{b} \div \frac{c}{d} = \frac{a}{b} \times \frac{d}{c}

= \frac{16}{1} \times \frac{5}{4}

Cross-cancel common factor:

4

= \frac{4}{1} \times \frac{5}{1}

Multiply fractions:

\frac{a}{b} \times \frac{c}{d} = \frac{a \times c}{b \times d}

= \frac{4 \times 5}{1 \times 1}

Multiply the numbers:

4 \times 5 = 20

= \frac{20}{1 \times 1}

Multiply the numbers:

1 \times 1 = 1

= \frac{20}{1}

Apply rule

\frac{a}{1} = a

= 20

1 \frac{1}{2} - \frac{3}{4}

\frac{x}{3 x ^{2} y} + \frac{x + 1}{6 x y ^{2}} - \frac{3}{9 x y}

\frac{\frac{1}{2} x ^{2}}{\frac{2}{3}}
