Milena just turned 11 years old. How old was she 2 1/4 years ago?

Milena was 9 years and 3 months old

Milena was 8 years and 9 months old.

Step-by-step explanation:

11 - 2 = 9

12 divided by 4 = 3

3 x 1 = 3

12 - 3 = 9

Explanation:

Milena would have been 8 years and 9 months old because 2 years before she had just turned 11 she would have just turned 9. And 1/4 a year before she turned 9 she would have been 8 years and 9 months because 1/4 a year equals 3 months.
