Interactive unit rate quiz for 7th graders

📚 Quick Study Guide

• ➗ A unit rate compares a quantity to one unit of another quantity.
• ✍️ To find a unit rate, divide the numerator and denominator of a rate by the denominator. For example, if you travel 120 miles in 2 hours, the unit rate is $\frac{120 \text{ miles}}{2 \text{ hours}} = 60$ miles per hour.
• 💰 Unit rates often involve prices. For example, finding the price per apple when you buy a bag of apples.
• 💡 When comparing unit rates, the lower price is usually the better deal!
• 📏 Remember to include the units in your answer (e.g., miles per hour, dollars per pound).
