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**
