Sometimes in maths, we are presented with a written problem rather than a sum!
When these questions appear, we must always still use our maths knowledge to solve the question and not be put off by the words!
We need to think carefully about which maths knowledge we should use each time.
Given that 37 × 22 = 814, can you find 37 × 2.2 without further working?
Did you spot the part that said 'without further working'? There must be some maths understanding we can apply to work this answer out without a calculator or further sums... but what is it?
We need to look at the relationship between the numbers. Did you spot that 2.2 is a tenth of 22?
When we divide a number by 10, we move the decimal point once to the left
37 × 2.2 = 814 ÷ 10 = 81.4
Was that easier than it looked?
Let's give this a go!
