Dividing $3.99 ÷ 24

Divide $\$3.99 \div 24$ by applying the decimal division procedure and rounding the result to the nearest cent:

Set up the division: The divisor $24$ is already a whole number, so no decimal-point shifting is needed. Place the decimal point in the quotient directly above the decimal point in the dividend $3.99$ .
Extend the dividend: Because the answer involves money, it must be rounded to the nearest cent — the hundredths place. To round correctly, the division must be carried out to the thousandths place. Append a zero to the dividend, making it $3.990$ .
Perform long division:
- $24$ into $39$ : $1$ time ( $24$ ), remainder $15$ .
- Bring down $9$ : $24$ into $159$ : $6$ times ( $144$ ), remainder $15$ .
- Bring down $0$ : $24$ into $150$ : $6$ times ( $144$ ), remainder $6$ . The quotient so far is $0.166$ .
Round to the nearest cent: The hundredths digit is $6$ and the thousandths digit is also $6$ . Since $6 \geq 5$ , round up: $\$0.166 \approx \$0.17$ .

Therefore, $\$3.99 \div 24 \approx \$0.17$ . This example illustrates a key rule for money problems: always carry the division one place beyond the rounding target (to the thousandths place when rounding to the nearest cent) so that the rounding digit can be correctly determined.
