Answer:

3 1/6

Explanation:

First separate the whole number parts (the parts that aren't fractions or 4 and 1 in 4 1/2 and 1 1/3). We have to do 4-1, which is three, that will be our whole number in our answer. Now, we have 1/2 - 1/3. Find the LCM (least common multiple of 2 and 3.) 2, 4, 6, 8, 10 and 3,6,9,12,15. They share 6, so that will be our denominator. What do you multiply 2 by to get to 6? 3. What do you multiply 3 by to get to 6? 2. so multiply the 1 in 1/2 by 3 (since 2*3 is 6) and multiply the 1 in 1/3 by 2(since 3*2 is 6) and you get 3/6-2/6 which is 1/6, now put the whole number beside your fraction answer and you get 3 1/6.
