Hello there. To solve this question, we'll find how many times George's grandpa is older than his grandson.
First, this is also called the ratio of the ages between George and his grandpa.
To find this, we divide their ages in the order Grandpa : Grandson as following:
[tex]\frac{George^{\prime}s\text{ Grandpa age}}{\text{George's age}}=\text{ }\frac{72}{8}[/tex]Simplify the fraction by a factor of 8
[tex]9[/tex]This is how many times George's grandpa is older than him.
