Detailed Solution Examples
1 Length Problem Solution
Length Problem Solution
Problem: A pencil is 14 centimeters long. Sarah uses 6 centimeters of it. How long is the pencil now?
Definition:

Length conversion: 1 meter = 100 centimeters

Solution method:
  1. Identify the original length
  2. Identify the amount used
  3. Subtract to find remaining length
  4. Include the correct unit in your answer
14 cm total
6 cm used
8 cm remaining
Step-by-Step Solution:
Step 1: Original length = 14 cm
Step 2: Amount used = 6 cm
Step 3: Remaining length = 14 - 6 = 8 cm
Step 4: Check: 8 + 6 = 14 ✓
Answer: The pencil is 8 centimeters long.
The pencil is 8 centimeters long.

2 Weight Problem Solution
Weight Problem Solution
Problem: A bag of apples weighs 3 kilograms. If 800 grams are eaten, how much does the bag weigh now?
Definition:

Weight conversion: 1 kilogram = 1000 grams

⚖️
Start: 3 kg
→ -800 g
= 2 kg 200 g
Step-by-Step Solution:
Step 1: Convert to same units: 3 kg = 3000 g
Step 2: Amount eaten = 800 g
Step 3: Remaining weight = 3000 - 800 = 2200 g
Step 4: Convert back: 2200 g = 2 kg 200 g
Step 5: Check: 2 kg 200 g + 800 g = 3 kg ✓
Answer: The bag weighs 2 kilograms and 200 grams.
The bag weighs 2 kilograms and 200 grams.
Final Answer:

The bag weighs 2 kilograms and 200 grams.

Applied rules:

• Conversion: 1 kg = 1000 g

• Unit standardization: Convert to same units before calculation

• Regrouping: Convert back to mixed units if needed

3 Capacity Problem Solution
Capacity Problem Solution
Problem: A water bottle holds 1 liter 250 milliliters. If 450 milliliters are drunk, how much water remains?
Definition:

Capacity conversion: 1 liter = 1000 milliliters

🥤
1 L 250 mL
→ -450 mL
= 800 mL
Step-by-Step Solution:
Step 1: Convert to same units: 1 L 250 mL = 1250 mL
Step 2: Amount drunk = 450 mL
Step 3: Remaining = 1250 - 450 = 800 mL
Step 4: Convert back if needed: 800 mL = 0 L 800 mL
Step 5: Check: 800 mL + 450 mL = 1250 mL ✓
Answer: There are 800 milliliters of water remaining.
There are 800 milliliters of water remaining.
Final Answer:

There are 800 milliliters of water remaining.

Applied rules:

• Conversion: 1 L = 1000 mL

• Subtraction: For finding remaining amounts

• Verification: Check calculation with reverse operation

4 Time Problem Solution
Time Problem Solution
Problem: A movie starts at 2:45 PM and lasts 1 hour 35 minutes. What time does it end?
Definition:

Time conversion: 1 hour = 60 minutes

🕐
Start: 2:45 PM
+1h35m
= 4:20 PM
Step-by-Step Solution:
Step 1: Start time = 2:45 PM
Step 2: Duration = 1 hour 35 minutes
Step 3: Add hours: 2 + 1 = 3
Step 4: Add minutes: 45 + 35 = 80 minutes = 1 hour 20 minutes
Step 5: Total: 3 + 1 hour 20 minutes = 4:20 PM
Step 6: Check: 4:20 PM - 1:35 = 2:45 PM ✓
