**Educational Worksheet** 1. **Problem 1:** Sasha hikes into a canyon. She takes a break at rest stations every \(2 \frac{2}{3}\) miles she descends. If she started at sea level and has hiked down to the fourth rest station, what is Sasha’s elevation now?\ - **Solution:** Multiplying \(2 \frac{2}{3}\) by 4 gives \(10 \frac{2}{3}\) miles below sea level. 2. **Problem 2:** Find the product of \(-\frac{3}{5} \cdot -1.5\).\ - **Options:** - A. \(-1 \frac{3}{25}\) - B. \(-0.09\) - C. \(\frac{3}{25}\) - D. \(0.9\) - **Solution:** D. \(0.9\) 3. **Problem 3:** Jenny has $2.40 deducted from her monthly allowance every time she forgets to do a chore. If she forgets three times in one month, what will be the change in Jenny’s total allowance?\ - **Solution:** $7.20 deduction. 4. **Problem 4:** An airplane descends at a rate of 2,700 feet per minute. Once the airplane starts its descent, what will be its change in elevation after \(3 \frac{1}{2}\) minutes?\ - **Solution:** The elevation will change by 9,450 feet. 5. **Problem 5:** How does the number line below represent the product of a positive number and a negative number? Explain.\ - **Diagram Explanation:** The number line shows movement from 0 to negative values, illustrating how multiplying a positive number by a negative number results in a negative product.\ - **Explanation:** Each arc on the number line represents multiplication steps, resulting in values moving left on the number line. **Diagram:** - A number line is shown with arcs from 0 moving incrementally to negative values between 0 and -5, depicting the multiplication process.
