QUESTION 1 of 10

Percentages are simply another way of expressing hundredths.

'Per cent' means 'out of a hundred'.

So 1% = 1/100 = 0.01

10% = 10/100 = 0.10 = 0.1

20% = 20/100 = 0.20 = 0.2

43% = 43/100 = 0.43

Remember that 50% and 5% are very different:

50% = 0.50 = 0.5

5% = 0.05

A method

When we convert from a percentage to a decimal, we are actually dividing by 100.

So...

47% = 47 ÷ 100 = 0.47

7% = 7 ÷ 100 = 0.07
