Estimate 1 Exact $1 \frac{1}{6}$
$4 \frac{3}{8} \div 3 \frac{3}{4}$ Estimate $4 \div 4 = 1$ Exact $4 \frac{3}{8} \div 3 \frac{3}{4}$ = $\frac{35}{8} \div \frac{15}{4}$ = $\frac{35}{8} \times \frac{4}{15}$ = $\frac{35}{2} \times \frac{1}{15}$ = $\frac{35}{30}$ = $1 \frac{5}{30}$ = $1 \frac{5 \div 5}{30 \div 5}$ =$1 \frac{1}{6}$
