Grade 6 Decimal × and ÷ worksheet
from Gradelings · Name: ______________________
How to explain it
- Multiply as if there were no decimal points.
- Count the decimal places in the numbers you started with.
- Give your answer that many decimal places.
Example: 0.6 × 4 = ? Ignore the point: 6 × 4 = 24. 0.6 has 1 decimal place. So the answer has 1 decimal place: 2.4. Answer: 2.4
Question 1
What is 4.57 × 3?
4.57 × 3 = ?
answer box
13.71
Hint: Multiply as if there were no decimal point: 457 × 3 = 1371. 4.57 has 2 decimal places, so the answer does too.
Question 2
What is 1.3 × 0.7?
1.3 × 0.7 = ?
answer box
0.91
Hint: Multiply the whole numbers: 13 × 7 = 91. There are 2 decimal places in the factors altogether, so count 2 places from the right.
Question 3
What is 0.92 ÷ 4?
0.92 ÷ 4 = ?
answer box
0.23
Hint: Think of 0.92 as 92 hundredths. Divide: 92 ÷ 4 = 23 hundredths. Then write that as a decimal.
Question 4
Zoe buys 5 tennis balls at $2.20 each. What is the total cost in dollars?
🎾$2.20 eachanswer box
11
Hint: Multiply the price by 5. It can help to work in cents: 220¢ × 5, then change cents to dollars (100¢ = $1).
Question 5
56 × 64 = 3584. Use this fact to find 5.6 × 6.4.
56 × 64 = 3584
- 0.3584
- 3584
- 35.84
- 3.584
35.84
Hint: The digits come from 3584. Count the decimal places in both factors (2 in total), then move the decimal point in 3584 that many places to the left.
Question 6
47.5 L of juice is poured equally into 5 bottles. How much juice goes in each bottle?
answer boxL
9.5 L
Hint: Divide the total by 5: 47.5 ÷ 5. Think of 47.5 as 475 tenths to make it easier.
Question 7
Which is the best estimate for 8.16 × 4.3?
- 3.2
- 3200
- 32
- 320
32
Hint: Round each number to the nearest whole number, then multiply: 8 × 4. Check that the size of the answer makes sense.
Question 8
How many 0.25 L cups can be filled from 2.25 L of water?
answer box
9
Hint: Divide 2.25 by 0.25. Multiply both numbers by 100 to get whole numbers first: 225 ÷ 25.
Question 9
Which is the best estimate for 7.23 × 3.7?
- 280
- 2.8
- 2800
- 28
28
Hint: Round each number to the nearest whole number, then multiply: 7 × 4. Check that the size of the answer makes sense.
