Answer 2

Calculation of Age Difference

To determine how many years older the father was than Denis 4 years ago, we need to subtract Denis's age from his father's age at that time.

Given: - Denis is currently 13 years old. - His father is currently 40 years old.

To calculate the age difference 4 years ago, we subtract 4 from both Denis's and his father's current ages:

Denis's age 4 years ago: 13 - 4 = 9 years old Father's age 4 years ago: 40 - 4 = 36 years old

Therefore, the father was 4 years older than Denis 4 years ago.

Calculation of Age Difference Ratio

To determine how many times older the father was than Denis 4 years ago, we need to divide the father's age by Denis's age 4 years ago.

Given: - Denis's age 4 years ago: 9 years old - Father's age 4 years ago: 36 years old

To calculate the age difference ratio, we divide the father's age by Denis's age:

Age difference ratio: 36 / 9 = 4

Therefore, the father was 4 times older than Denis 4 years ago.
