Since you got 16/12 when you solved the equation, what you do is first look at the fraction. It's an improper fraction, where as the numerator is greater than the denominator. 12 goes into 16 1 time so the whole number is 1. Then, you're left with 4/12. That 4/12 simplifies into 1/3. So the answer simplified is 1 1/3. 1 1/3 is a mixed number.
