Answer:
Age of Kofi = 10 years
Age of Yaw = 15 years
Age of Kwaku = 25 years
Step-by-step explanation:
Framing algebraic equations and solving:
Ratio of ages = 2 : 3 :5
Age of Kofi = 2x
Age of Yaw = 3x
Age of Kwaku = 5x
Difference between Kofi's age and Kwaku's age = 15 years
5x - 2x = 15 years
Combine like terms,
3x = 15
Divide both sides by 3,
x = 15 ÷ 3
x = 5
Age of Kofi = 2*5 = 10 years
Age of Yaw = 3*5 = 15 years
Age of Kwaku = 5*5 = 25 years
