Answer:
5 years old
Step-by-step explanation:
The first thing you should do is find 1/4 of his brother's age. To find this, you divide his age by 4.
12/4 = 3
You will receive 3 as the answer.
The problem also states that he is 2 years older than 1/4 of his age, meaning he is 2 years older than three.
3 + 2 = 5
Therefore, Justin is 5 years old.
