## Part : Part Ratio

If three people (Amy, Bob and Cara) divide up £5400 in the ratio 2 : 3 : 4, how much money does each of them get?

### Find number of parts

• If three people (Amy, Bob and Cara) divide up £5400 in the ratio 2 : 3 : 4 then there are 9 parts in total.
• 2 + 3 + 4 = 9.

### Find value of each part and multiply

• Each part is worth £5400 ÷ 9 = £600:
• Amy gets 2 × £600 = £1200.
• Bob gets 3 × £600 = £1800.
• Cara gets 4 × £600 = £2400.

### Checking

• Check the result by adding these quantities and checking it is the same as the original.
