Solution steps

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

Convert mixed numbers to improper fractions:

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

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

Convert mixed numbers to improper fractions:

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

= \frac{9}{2} \div \frac{3}{2}

Apply the fraction rule:

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

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

Multiply fractions:

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

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

Cancel the common factor:

2

= \frac{9}{3}

Divide the numbers:

\frac{9}{3} = 3

= 3

\frac{x + 4}{4 + x}

y - y^{2}

s (s + 1) (s + 2) (s + 3)

- \frac{3}{12}

f (x) + 1
