Unit rate test questions for 6th grade math

📚 Quick Study Guide

🔢 Unit rate is a ratio that compares a quantity to one unit of another quantity. For example, miles per hour (mph) or cost per item. ➗ To find the unit rate, divide the quantity by the number of units. If it costs $6 for 3 apples, the unit rate is $6 ÷ 3 = $2 per apple. 📝 Use the formula: Unit Rate = $\frac{\text{Quantity}}{\text{Number of Units}}$ 💰 Always remember to include the units in your answer (e.g., dollars per hour, miles per gallon). 💡 Pro-tip: When comparing unit rates, the lower unit rate is usually the better deal if you are buying something (like groceries).
