Explanation:
Since the ratio is 5:3, then we can divide 60 by 5 to find out how much we should be multiplying 3 by.
60÷5=12
Since the result is 12, then we have to multiply 3 by 12 to get the son's age.
3×12=36.
So, the son's age is 36.
We can check this by dividing both sides by 12 and if we get 5:3, then it is correct.
60÷12=5
36÷12=3
Ratio: 5:3
So, it is correct.
