Calculating Age Difference

To find out how many years younger Olena is than her older brother, we can use the given information that Olena is 12 years old and her age is 0.8 of her older brother's age.

Step 1: Calculate the age of Olena's older brother. Step 2: Find the age difference between Olena and her older brother.

Let's proceed with the calculations.

Step 1:

The age of Olena's older brother can be calculated by dividing Olena's age by 0.8. So, Olena's older brother's age = 12 / 0.8 = 15 years.

Step 2:

Now, we can find the age difference between Olena and her older brother. Age difference = Older brother's age - Olena's age = 15 - 12 = 3 years.

Therefore, Olena is 3 years younger than her older brother.

This calculation is based on the given information and the mathematical operations performed.
