In this worksheet, you must remember that:

1/10 = 0.1 = 10%

2/10 = 0.2 = 20%

3/10 = 0.3 = 30% etc.

1/25 = 0.04 = 4%

1/50 = 0.02 = 2%

**Example 1**

Jack has £40 and spends 30% of it.

How much does he have left?

**Answer**

30% = 3/10

First, find 3/10 of £40.

1/10 of £40 = £40 ÷ 10 = £4

So 3/10 of £40 = 3 × £4 = £12.

So Jack spends £12 and has £40 - £12 =** £28 left.**

**Example 2**

Which is bigger, 4/10 of £100 or 4% of £1000?

**Answer**

1/10 of £100 = £100 ÷ 10 = £10

4/10 of £100 = 4 × £10 = **£40**

4% = 1/25

1/25 of £1000 = £1000 ÷ 25 =** £40**

**They are the same.**
