Answer:

40%

Explanation:

The ratio is 3 : 2, gold to silver.

He has 3x gold coins and 2x silver coins.

the total number of coins is 5x.

percent = part/whole × 100%

percent of gold coins = (2x)/(5x) × 100%

percent of gold coins = 2/5 × 100%

percent of gold coins = 0.4 × 100%

percent of gold coins = 40%
