Wages are paid to Jack and Oliver. Jack received £30, while Oliver received £50. What was the ratio for the amount paid out between Jack and Oliver? Give the ratio in its simplest form.

The amount paid out was in the ratio 30:50, which simplifies to 3:5 (divide both by 10).

The fraction earned by Oliver was frac(50)(80) which simplifies to frac(5)(8)
Answer: frac(5)(8)
