Machine Bread Production Calculation Result Grade 5 Class Gender Ratio Computation

Let's solve each question step by step: --- **1. A machine can produce 10 loaves of bread in 2 minutes. How many loaves can the machine produce in 1.5 hours?** **Step 1: Find the number of loaves produced per minute.** - 10 loaves in 2 minutes - So, per minute: 10 loaves / 2 minutes = **5 loaves per minute** **Step 2: Find out how many minutes in 1.5 hours** - 1.5 hours = 1.5 × 60 = **90 minutes** **Step 3: Find total loaves in 90 minutes** - 5 loaves/minute × 90 minutes = **450 loaves** So, the answer is: **d. 450 loaves** --- **2. The ratio of boys to girls in the Grade 5 classes at Manaileng Primary school is 3:5. If there are 280 Grade 3 learners, how many are boys?** (Assuming 280 is the total number of learners in Grade 5, as grade 3 is probably a typo.) **Step 1: The ratio is 3 boys : 5 girls, so total parts = 3 + 5 = 8** **Step 2: Number of boys in 280 learners** - Boys = (3 / 8) × 280 = (3 × 280) / 8 = 840 / 8 = **105** So, the answer is: **d. 105** --- **Final Answers:** 1. **d. 450 loaves** 2. **d. 105**
