I am learning to solve “How many sets of ...” and “sharing” division
problems using multiplication.
12 ÷ ? = 3
3 X ? = 12
Angela has 18 counters to share between 3 groups. 18 ÷ 3 = ?
or 3 X ? = 18
Below are 3 groups.
Start by sharing 3 counters between the 3 groups.
3÷3=1
Now share 3 more between each group (this means
you will have shared 6 counters in total).
6÷3=2
Now share 3 more between each group (this means
you will have shared 9 counters in total).
9÷3=3
We have now shared out 9 of the 18 counters we need to. That’s half
of the counters.
That means we have to share the same amount again so
everyone will get 3 more counters. That’s 6 counters in total.
18 ÷ 3 = 6
Zoe has 42 sweets to share between 6 groups.
Below are 6 groups.
I know 6 X 5 = 30 so I’m going to start by sharing
out 30 sweets.
42 ÷ 6 = ?
or 6 X ? = 42
30 ÷ 6 = 5
I need to share out 42 sweets but I have only shared out 30. That
means I have 12 more sweets to share out.
6 X 2 = 12
or
12 ÷ 6 = 2
We have now shared out all 42 sweets. 5 sweets (the first amount we
shared + 2 sweets the second amount we shared = 7 sweets).
42 ÷ 6 = 7

Adam has 72 sweets to share between 8 groups.
Below are 8 groups.
I know 8 X 5 = 40 so I’m going to start by sharing
out 40 sweets.
72 ÷ 8 = ?
or 8 X ? = 72
40 ÷ 8 = 5
I need to share out 72 sweets but I have only shared out 40. That
means I have 32 more sweets to share out.
8 X 4 = 32
or
32 ÷ 8 = 4
We have now shared out all 72 sweets. 5 sweets (the first amount we
shared + 4 sweets the second amount we shared = 9 sweets).
72 ÷ 8 = 9
