Answer 3

Calculation of Age Difference

To determine how many years older the father was than Denis 4 years ago, we need to subtract 4 from the current ages of both Denis and his father.

Denis is currently 13 years old, and his father is currently 40 years old. Therefore, 4 years ago, Denis was 13 - 4 = 9 years old, and his father was 40 - 4 = 36 years old.

Age Difference 4 Years Ago

To calculate how many years older the father was than Denis 4 years ago, we subtract Denis's age from his father's age 4 years ago.

The father was 36 years old, and Denis was 9 years old 4 years ago. Therefore, the father was 36 - 9 = 27 years older than Denis 4 years ago.

Ratio of Age Difference

To determine the ratio of how much older the father was than Denis 4 years ago, we divide the father's age difference by Denis's age difference.

The father was 27 years older than Denis 4 years ago. Therefore, the ratio of how much older the father was than Denis 4 years ago is 27:4, or 6.75 times older.
