Capacity Worksheets - Free Printable

Problem Analysis:

The worksheet involves measuring jugs and performing arithmetic operations to determine the new readings, required amounts of water, or amounts to be poured out. Each question requires careful observation of the initial water levels in the jugs and applying basic addition or subtraction.

---

Question 1: If you add 200 mL of water in each jug, what would be the new reading?

#### Part (a):
- Initial Reading: The water level in the jug is at 500 mL.
- Water Added: 200 mL
- New Reading Calculation:
\[
\text{New Reading} = \text{Initial Reading} + \text{Water Added} = 500 \, \text{mL} + 200 \, \text{mL} = 700 \, \text{mL}
\]
- Answer for (a): \( \boxed{700} \)

#### Part (b):
- Initial Reading: The water level in the jug is at 300 mL.
- Water Added: 200 mL
- New Reading Calculation:
\[
\text{New Reading} = \text{Initial Reading} + \text{Water Added} = 300 \, \text{mL} + 200 \, \text{mL} = 500 \, \text{mL}
\]
- Answer for (b): \( \boxed{500} \)

Question 2: How much water is required to fill each jug up to 800 mL?

#### Part (a):
- Initial Reading: The water level in the jug is at 250 mL.
- Target Reading: 800 mL
- Water Required Calculation:
\[
\text{Water Required} = \text{Target Reading} - \text{Initial Reading} = 800 \, \text{mL} - 250 \, \text{mL} = 550 \, \text{mL}
\]
- Answer for (a): \( \boxed{550} \)

#### Part (b):
- Initial Reading: The water level in the jug is at 500 mL.
- Target Reading: 800 mL
- Water Required Calculation:
\[
\text{Water Required} = \text{Target Reading} - \text{Initial Reading} = 800 \, \text{mL} - 500 \, \text{mL} = 300 \, \text{mL}
\]
- Answer for (b): \( \boxed{300} \)

---

Question 3: How much water should you pour out from each jug to drop the water level down to 300 mL?

#### Part (a):
- Initial Reading: The water level in the jug is at 500 mL.
- Target Reading: 300 mL
- Water to Pour Out Calculation:
\[
\text{Water to Pour Out} = \text{Initial Reading} - \text{Target Reading} = 500 \, \text{mL} - 300 \, \text{mL} = 200 \, \text{mL}
\]
- Answer for (a): \( \boxed{200} \)

#### Part (b):
- Initial Reading: The water level in the jug is at 800 mL.
- Target Reading: 300 mL
- Water to Pour Out Calculation:
\[
\text{Water to Pour Out} = \text{Initial Reading} - \text{Target Reading} = 800 \, \text{mL} - 300 \, \text{mL} = 500 \, \text{mL}
\]
- Answer for (b): \( \boxed{500} \)

Final Answers:

1. a) \( \boxed{700} \), b) \( \boxed{500} \)
2. a) \( \boxed{550} \), b) \( \boxed{300} \)
3. a) \( \boxed{200} \), b) \( \boxed{500} \)

Explanation:

- Question 1: Addition is used to find the new reading after adding water.
- Question 2: Subtraction is used to determine how much more water is needed to reach the target level.
- Question 3: Subtraction is used to calculate how much water needs to be removed to reach the target level.

Each step involves straightforward arithmetic based on the initial and target readings of the measuring jugs.
