Step-by-step solution for: Long Division Worksheets -Worksheets Library
Problem Overview:
The task involves solving division problems where the divisor is a whole number, and the dividend includes decimals. The goal is to perform long division while handling the decimal points correctly.
Solution Approach:
1. Understand the Decimal Placement: When dividing a number with a decimal by a whole number, the decimal point in the quotient aligns directly above the decimal point in the dividend.
2. Perform Long Division: Treat the division as if both numbers were whole numbers, but remember to place the decimal point in the quotient at the correct position.
3. Continue Dividing: If necessary, add zeros to the right of the decimal in the dividend to complete the division.
Step-by-Step Solutions:
#### 1. \( 7 \div 5.67 \)
- Perform \( 5.67 \div 7 \):
- Move the decimal point in both numbers to make the divisor a whole number: \( 567 \div 700 \).
- Perform the division: \( 567 \div 7 = 81 \).
- Place the decimal point: \( 0.81 \).
Answer: \( 0.81 \)
#### 2. \( 4 \div 3.54 \)
- Perform \( 3.54 \div 4 \):
- Move the decimal point: \( 354 \div 400 \).
- Perform the division: \( 354 \div 4 = 88.5 \).
- Place the decimal point: \( 0.885 \).
Answer: \( 0.885 \)
#### 3. \( 6 \div 4.98 \)
- Perform \( 4.98 \div 6 \):
- Move the decimal point: \( 498 \div 600 \).
- Perform the division: \( 498 \div 6 = 83 \).
- Place the decimal point: \( 0.83 \).
Answer: \( 0.83 \)
#### 4. \( 2 \div 6.98 \)
- Perform \( 6.98 \div 2 \):
- Move the decimal point: \( 698 \div 200 \).
- Perform the division: \( 698 \div 2 = 349 \).
- Place the decimal point: \( 3.49 \).
Answer: \( 3.49 \)
#### 5. \( 5 \div 4.56 \)
- Perform \( 4.56 \div 5 \):
- Move the decimal point: \( 456 \div 500 \).
- Perform the division: \( 456 \div 5 = 91.2 \).
- Place the decimal point: \( 0.912 \).
Answer: \( 0.912 \)
#### 6. \( 9 \div 7.38 \)
- Perform \( 7.38 \div 9 \):
- Move the decimal point: \( 738 \div 900 \).
- Perform the division: \( 738 \div 9 = 82 \).
- Place the decimal point: \( 0.82 \).
Answer: \( 0.82 \)
#### 7. \( 8 \div 6.24 \)
- Perform \( 6.24 \div 8 \):
- Move the decimal point: \( 624 \div 800 \).
- Perform the division: \( 624 \div 8 = 78 \).
- Place the decimal point: \( 0.78 \).
Answer: \( 0.78 \)
#### 8. \( 5 \div 3.55 \)
- Perform \( 3.55 \div 5 \):
- Move the decimal point: \( 355 \div 500 \).

- Place the decimal point: \( 0.71 \).
Answer: \( 0.71 \)
#### 9. \( 6 \div 3.96 \)
- Perform \( 3.96 \div 6 \):
- Move the decimal point: \( 396 \div 600 \).
- Perform the division: \( 396 \div 6 = 66 \).
- Place the decimal point: \( 0.66 \).
Answer: \( 0.66 \)
#### 10. \( 9 \div 7.65 \)
- Perform \( 7.65 \div 9 \):
- Move the decimal point: \( 765 \div 900 \).
- Perform the division: \( 765 \div 9 = 85 \).
- Place the decimal point: \( 0.85 \).
Answer: \( 0.85 \)
#### 11. \( 8 \div 6.32 \)
- Perform \( 6.32 \div 8 \):
