The ages of a father and son are in the ratio of 8:3. If the farther is 48, how old is the son?

fathers age ---- 8x

son's age ----- 3x

but 8x = 48
x = 6
so the son is 18

or , just using a ratio ....

48/s = 8/3
8s = 144
s = 144/8 =18

To find the age of the son, we first need to calculate the common ratio between the ages of the father and son.

The given ratio is 8:3, which represents the father's age to the son's age. We know that the father's age is 48.

To determine the common ratio, we can set up a proportion using the given information:

8/3 = 48/x

To solve for x, we can cross-multiply:

8x = 48 * 3

8x = 144

Next, we divide both sides of the equation by 8 to isolate x:

x = 144/8

x = 18

Therefore, the son is 18 years old.
