The activity sheet is asking you to determine whether each of the pairs of quantities is a rate, and if it is, convert it into a unit rate. Here's an explanation for each of the pairs:

1. **5 humans to 10 hands**  
   **Not a rate (N)** – This is a simple ratio because it's just a count of humans to their hands, not a measure per unit of time or quantity. It doesn’t require conversion to a unit rate.

2. **₱300 per 2 hours of work**  
   **Rate (R)** – This is a rate because it's money per time unit (₱/hour).  
   **Unit Rate:** ₱300 ÷ 2 = **₱150 per hour**.

3. **₱300 to 2 kg of rambutan**  
   **Rate (R)** – This is a rate because it's cost per unit of weight (₱/kg).  
   **Unit Rate:** ₱300 ÷ 2 = **₱150 per kg**.

4. **20 meters in 5 seconds**  
   **Rate (R)** – This is a rate because it's distance per time (meters/second).  
   **Unit Rate:** 20 ÷ 5 = **4 meters per second**.

5. **24 miles in every 8 hours**  
   **Rate (R)** – This is a rate because it’s distance per time (miles/hour).  
   **Unit Rate:** 24 ÷ 8 = **3 miles per hour**.

6. **₱30,000 in 3 square meters**  
   **Rate (R)** – This is a rate because it’s money per area (₱/square meter).  
   **Unit Rate:** ₱30,000 ÷ 3 = **₱10,000 per square meter**.

7. **60 seconds per minute**  
   **Not a rate (N)** – This is not a rate because it's a conversion of time, not two different types of quantities.

8. **6 inches in half a ruler**  
   **Rate (R)** – This is a rate because it's length per unit of measurement (inches per ruler fraction).  
   **Unit Rate:** 6 ÷ 0.5 = **12 inches per full ruler**.

9. **6 apples in 3

The activity sheet is asking you to determine whether each of the pairs of quantities is a rate, and if it is, convert it into a unit rate.

This activity helps Grade 7 students identify rates and convert them into unit rates. Key concepts include cost per weight, distance per time, and price per area. Examples include ₱300 for 2 hours of work, 24 miles in 8 hours, and ₱30,000 in 3 square meters.
