Final answer:
Jamie's age is calculated by dividing his father's age (36 years) by 4, resulting in Jamie being 9 years old.
Step-by-step explanation:
If Jamie's father is 36 years old and Jamie is ¼ as old as his father,
we can calculate Jamie's age by dividing the father's age by 4.
So, the calculation involved is 36 divided by 4, which equals 9. Therefore, Jamie is 9 years old.
