b
You could start with 400 × 6 or 800 × 3. It is up to you.
3
Complete the missing steps. The first one has been done for you.
a
0.3 × 6
First work out: 3 × 6 = 18
so 0.3 × 6 = 1.8
b
0.2 × 8
First work out: 2 × 8 = ……
so 0.2 × 8 = ……
c
0.4 × 4
First work out: 4 × 4 = ……
so 0.4 × 4 = ……
d
0.7 × 9
First work out: …… × …… = ……
so 0.7 × 9 = ……
e
0.5 × 5
First work out: …… × …… = ……
so 0.5 × 5 = ……
