\frac{9}{4} \div 2

Convert element to fraction:

2 = \frac{2}{1}

= \frac{9}{4} \div \frac{2}{1}

Apply the fraction rule:

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

= \frac{9}{4} \times \frac{1}{2}

Multiply fractions:

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

= \frac{9 \times 1}{4 \times 2}

Multiply the numbers:

9 \times 1 = 9

= \frac{9}{4 \times 2}

Multiply the numbers:

4 \times 2 = 8

= \frac{9}{8}

1 + x (x + 1) (x + 2) (x + 3)

32 \cdot \frac{1}{2}

(4 x^{2} - 2 x y + 5) - (x^{2} + x y - 1)

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

\frac{9}{121}
