Step-by-step solution for: Dividing Fractions Worksheet
The image shows a worksheet titled "Dividing Fractions Sheet 5," which involves dividing fractions. The task is to solve each division problem and express the answer as a mixed number if possible, rounded to two decimal places.
1. Understand the Rule: To divide fractions, you multiply the first fraction by the reciprocal of the second fraction.
- If you have \( \frac{a}{b} \div \frac{c}{d} \), it becomes \( \frac{a}{b} \times \frac{d}{c} \).
2. Simplify: After multiplying, simplify the resulting fraction if possible. If the result is an improper fraction (numerator > denominator), convert it to a mixed number.
3. Round: If the result is a decimal, round it to two decimal places.
