in order to find the mixed number you need to know what the denominator (the bottom number) is. In your case, its 3. So the next thing you need to know is the whole number. There are 4. So multiply 4*3 because you have filled the fraction 4 times. so 4*3=12
so the next thing you do is add the two in the equation to the twelve.
so your answer would be 14/3
