hope it helps!

please mark as brainliest!!

thanks!!!

Step-by-step explanation:

first, we will put this in numerical form:

lets say that a is the age of the father and b is the age of the son. then,

a=3b

a+b=60

now, we can substitute a with 3b as a=3b.

3b+b = 60

4b = 60

b = 60/4

b = 15

hence, the age of the son is 15.

a = 3b = (3x15) = 45

hence, the age of his father is 45.

Answer 2

Step-by-step explanation:

Let us assume the age of the son is x.

So, the father's age will be 3x.

The ratio of the son: father will be x: 3x.

x + 3x = 4x (Parts)

$\frac{60}{4}$ = 15 years (1 part)

Son's age: x = 15 years.

Father's age: 3x = 3 * 15

                           = 45 years.
