Answer 1

Через 9 лет. Дочери будет 15 лет , а отцу 45. 15×3=45 45:3=15 Значит отец в 3 раза старше дочери

Answer 2

Calculating the Age Difference:

To calculate the number of years it will take for the father to be three times as old as his daughter, we can use the following approach:

Let's denote the daughter's current age as d and the father's current age as f. We are looking for the number of years, denoted as y, after which the father will be three times as old as the daughter. Mathematically, this can be represented as:

f + y = 3 * (d + y)

Solving for the Number of Years:

Using the given ages of the daughter and the father, we can solve for the number of years, y:

1. d = 6 (Daughter's age) 2. f = 36 (Father's age)

Substituting these values into the equation, we get:

36 + y = 3 * (6 + y)

Let's solve for y.

Solution:

36 + y = 18 + 3y

36 - 18 = 3y - y

18 = 2y

y = 9

Answer:

After 9 years, the father will be three times as old as his daughter.
