The worksheet you're working with asks whether each pair of quantities represents a rate. Let's analyze each pair:

1. **5 humans to 10 hands**: 
   - This does **not** represent a rate. It is a simple ratio, as it compares quantities directly without implying a per-unit relationship over time or distance.

2. **₱300 per 2 hours of work**: 
   - This **is** a rate. It expresses an amount of money earned per unit of time (₱300 per 2 hours).

3. **₱300 to 2 kg of rambutan**:
   - This does **not** represent a rate. Like the first one, it's a ratio rather than a rate. It compares money to mass without involving a per-unit concept.

4. **20 meters in 5 seconds**:
   - This **is** a rate. It describes speed (distance per unit of time).

5. **24 miles in every 8 hours**:
   - This **is** a rate. It expresses speed or distance covered over time.

6. **₱30,000.00 in 3 square meters**:
   - This **is** a rate. It represents cost per area (₱ per square meter).

7. **60 seconds per minute**:
   - This **is** a rate, as it expresses time per unit of another time (though the rate is constant by definition).

8. **6 inches in half ruler**:
   - This does **not** represent a rate. It simply states a length relative to a part of an object (the ruler).

9. **6 apples in 3 oranges**:
   - This does **not** represent a rate. It is just a ratio comparing two quantities.

10. **15 candies in every ₱60.00**:
    - This **is** a rate. It describes the number of candies per amount of money.

### Tip:
When identifying rates, look for units that are different and usually involve time, distance, or a per-item basis (e.g., per hour, per mile, per dollar).
