How it works
Deal them out until none are left. Count one group.
8 ÷ 4 asks: how many groups of 4 are in 8?
Use a times fact: ? × 4 = 8.
Example 1: How many groups?
- How many groups of 4 in 8? 8 ÷ 4 = ?
- How many groups of 4 are in 8?
- 2 groups of 4 make 8.
- So the answer is 2.
Example 2: Find the first number
- Find 10 ÷ 5. ? × 5 = 10
- Think what times 5 makes 10.
- 2 × 5 = 10.
- So the answer is 2.
Example 3: Find the divisor
- 21 in groups of 7. 21 ÷ ? = 7
- 21 in groups of 7 gives 3 groups.
- 3 groups, because 3 × 7 = 21.
- So the answer is 3.
Words to know
- divisor
- The number you divide by.
- quotient
- The answer to a division.
Watch out
- Check by multiplying back.
- Division can mean sharing or grouping.
- Every share must be equal.
Try it
- Find 9 ÷ 3. ? × 3 = 9
- How many groups of 5 in 35? 35 ÷ 5 = ?
- Find 24 ÷ 4. ? × 4 = 24
