Денису 13 лет, а папе 40 лет. На сколько лет папа был старше Дениса 4 года назад? Во сколько раз папа был старше Дениса 4 года назад?

Answer 1

40-13=27 (лет) - настолько лет папа старше Дениса всего
27-4=23 (года) - настолько лет папа был старше Дениса 4 года назад
(13-4)=9 - столько лет было Денису 4 года назад
23:9=2,56
Ответ: 2,56

Answer 2

(40-4)-(13-4)=27(на 27 лет)-папа был старше Дениса 4года назад
(40-4):(13-4)=3(в 3раза)папа был старше Дениса 4 года назад

Answer 3

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 and then subtract 4 from the result.

Denis is currently 13 years old, and his father is 40 years old.

To find the age difference 4 years ago, we subtract 4 from both Denis's and his father's 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 divide the father's age 4 years ago by Denis's age 4 years ago.

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

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

36 / 9 = 4

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