Leonard is 4 years younger than Nina who is half as old as Jerome. If the sum of their ages is 36, what is Leonard's age?
Let's think step by step below.
6
Let x be the age of Nina.

So, Leonard's age is x - 4.

And Jerome's age is 2x.

Since the sum of their ages is 36, then the equation is x + x - 4 + 2x = 36.

By combining like terms, the equation becomes 4x = 40.

So the value of x which represents the age of Nina is x = 40 / 4 = 10.

Therefore, Leonard is 10 - 4 = 6 years old.

.

So, the final answer is 6
