Answer:
1. Add up the ratio to find the total number of parts:
1 + 4 + 5 = 10 parts
2. Divide the total amount by the number of parts:
£80 ÷ 10 = £8
Each part is worth £8
3. Multiply by the ratio to find each share:
1 × £8 = £8
4 × £8 = £32
5 × £8 = £40
4. Check these add up to the original amount:
£8 + £32 + £40 = £80
