Division meaning answers: exercises 1 to 10

Exercise 1 – Sharing or grouping?

Each bag has a set size of 3, and we find the number of bags: grouping ($15 \div 3 = 5$ bags).
The total is split among 3 friends, and we find how many each gets: sharing ($15 \div 3 = 5$ apples each).

Exercise 2 – Counters in boxes

12 counters are shared equally in 3 boxes: $12 \div 3 = 4$. Check: $3 \times 4 = 12$. Answer: 4 counters in each box.

12 ÷ 3 = 4.

Exercise 3 – Boxes of five

Each box holds 5, so find how many 5s are in 15: $15 \div 5 = 3$. Check: $3 \times 5 = 15$. Answer: 3 boxes.

Exercise 4 – Apple baskets

$20 \div 4 = 5$. Check: $4 \times 5 = 20$. Answer: 5 apples.

Exercise 5 – Write the partner

Ask: 7 times what number is 28? The equation is $7 \times ? = 28$. Since $7 \times 4 = 28$, the unknown is 4. Answer: $28 \div 7 = 4$.

Exercise 6 – Find the missing factor

Count by 3s: 3, 6, 9, 12, 15, 18, 21, 24, 27. That is 9 numbers, so $3 \times 9 = 27$. Answer: 9.

Exercise 7 – Columns in an array

$24 \div 4 = ?$, and $4 \times 6 = 24$. Answer: 6 squares in each row.

6 squares in each of 4 rows.

Exercise 8 – Use a multiplication fact

The fact says 5 groups of 9 make 45, so 45 split into 5 groups gives 9 in each. Answer: $45 \div 5 = 9$.

Exercise 9 – Missing total

A total split into 4 groups gives 7 in each group, so the total is $4 \times 7 = 28$. Check: $28 \div 4 = 7$. Answer: 28.

Exercise 10 – Missing divisor

Ask: 6 times what number is 30? $6 \times 5 = 30$. Check: $30 \div 5 = 6$. Answer: 5.

Exercises 11 and up

Exercise 11 – Tape diagram of ribbons

$72 \div 8 = ?$, and $8 \times 9 = 72$. Answer: 9.

Each part is 9.

Exercise 12 – Equation with the unknown first

The right side must equal 5. A total split into 3 equal groups gives 5 in each, so the total is $3 \times 5 = 15$. Check: $15 \div 3 = 5$. Answer: 15.

Exercise 13 – Jumps of eight

Count the jumps: 4. Equation: $32 \div 8 = 4$. Check: $4 \times 8 = 32$. Answer: 4 jumps.

4 jumps of 8 reach 32.

Exercise 14 – True or false?

Multiply the quotient by the divisor: $7 \times 9 = 63$. This equals the dividend. Answer: True.

Exercise 15 – Stickers on pages

$45 \div 5 = 9$, because $5 \times 9 = 45$. Answer: 9 stickers.

Exercise 16 – Vans for a field trip

$42 \div 6 = 7$, because $6 \times 7 = 42$. Answer: 7 vans.

Exercise 17 – Peach crates

Step 1: $54 \div 6 = 9$. Step 2: $9 – 2 = 7$. Answer: 7 peaches.

Exercise 18 – Bead bracelets

Step 1: $36 \div 4 = 9$ beads on each bracelet. Step 2: $12 – 9 = 3$. Answer: 3 more beads.

Exercise 19 – Ribbon pieces

Step 1: $72 \div 9 = 8$ pieces. Step 2: $8 – 3 = 5$. Answer: 5 pieces.

Exercise 20 – Cookie boxes

Step 1: $64 \div 8 = 8$ boxes. Step 2: $8 \times 5 = 40$. Answer: $\$40$.

Key facts behind this division meaning answers

Key facts

Division finds the size of each group or the number of groups.
In 24 ÷ 4 = 6, the 24 is the dividend, the 4 is the divisor, and the 6 is the quotient.
Dividing 42 by 6 asks: 6 times what number makes 42?
An unknown can be in any spot, as in 8 × ? = 48, ? ÷ 3 = 5, or 24 ÷ ? = 8.
Check any division answer by multiplying the quotient by the divisor.
