Let 5x = Jaeden’s current age, and 3x = Kiernan’s current age. Then 5x + 3x = 32, so 8x = 32 and x = 4. Thus, Jaeden’s current age is 5x = 5(4) = 20, and Kiernan’s current age is 3x = 3(4) = 12. In 10 years, Jaeden and Kiernan will be 30 and 22, respectively, and the ratio of their ages will be 15:11.
