UNKNOWN IN MULTIPLICATION

1 There are 5 bowls of fish. The total number of fish
is m. Find the value of m.

5 × 7 = m
m = 5 × 7

m = 35

The value of m is 35.

Each fishbowl
has 7 fish.

2 k × 12 = 36 3 15 × p = 60 000
What is the value of k? What is the value of p?

Relate
multiplication Simple example.
to division. Simple example.
2 × 3 = 6 5 × 4 = 20

2 = 6 ÷ 3 4 = 20 ÷ 5

k × 12 = 36 15 × p = 60 000
k = 36 ÷ 12 p = 60 000 ÷ 15
k = 3 p = 4 000

3 × 12 = 36 15 × 4 000 = 60 000

The value of k is 3. The value of p is 4 000.

Find the values of h.
a 2 × 9 = h b h × 7 = 105
Given that 20 × 5 = n.
Find the value of n. c 50 × h = 20 000 d 13 × h = 65 260

38 • Carry out suitable simulation activities using concrete objects to
1.8.1 enhance pupils’ understanding in finding unknown values.
• Explain ‟simplify a case” strategy using small values to find unknown.
