The question
Question: work out 1.08 ÷ 0.12 × 0.3.
1.08 ÷ 0.12 × 0.3
1 Times and divide
Times and divide: we go from left to right.
Dividing by a decimal is hard.
We move the point 2 places to the right in both numbers.
That is times 100 for both, so the answer stays the same.
same kind: left → right
1.08 × 100 = 108
0.12 × 100 = 12
1.08 becomes 108.
0.12 becomes 12.
= 108 ÷ 12 × 0.3
108 divided by 12 is 9.
= 9 × 0.3
9 × 3 = 27
1 digit after the point → 2.7
Forget the points: 9 times 3 is 27.
The numbers have 1 digit after the point.
So the answer has 1 too: 2.7.
= 2.7
So the answer is 2.7.
Answer
= 2.7
