12/18 \div 45/9

\frac{12}{18} \div \frac{45}{9}

\frac{2}{15}

Solution steps

\frac{12}{18} \div \frac{45}{9}

Apply the fraction rule:

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

= \frac{12}{18} \times \frac{9}{45}

\frac{12}{18} = \frac{2}{3}

= \frac{2}{3} \times \frac{9}{45}

\frac{9}{45} = \frac{1}{5}

= \frac{2}{3} \times \frac{1}{5}

Multiply fractions:

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

= \frac{2 \times 1}{3 \times 5}

Multiply the numbers:

2 \times 1 = 2

= \frac{2}{3 \times 5}

Multiply the numbers:

3 \times 5 = 15

= \frac{2}{15}

(4 y + 3) - (2 y - 9)

\frac{- 72 i - 252 i}{2 ( - 108 - 54 i )}

x^{3} - 4 x^{2} - 4 x

4 x^{2} - 121 y^{2}

\frac{x + y ^{2}}{x ^{2}} + \frac{x - 1}{x} - 1
