Answer
Estimate $\frac{1}{2}$
Exact $\frac{1}{2}$
Work Step by Step
$1 \frac{1}{8} \div 2 \frac{1}{4}$
Estimate
Round to nearest whole number
$1 \div 2 = \frac{1}{2}$
Exact
Convert mixed numbers to improper fractions
$1 \frac{1}{8} \div 2 \frac{1}{4}$ = $\frac{9}{8} \div \frac{9}{4}$
Multiply by the inverse of the divisor
$\frac{9}{8} \times \frac{4}{9}$
Reduce fractions by the common factors of 9 and 4
$\frac{1}{2} \times \frac{1}{1}$ = $\frac{1}{2}$
