Jill brought 2 1/3 boxes of carrot muffins. Mike brought 1 3/4 of apple muffins. How many muffins are there in all?

4 1/12

Step-by-step explanation:

Let's go through this.

First, we have to find a common denominator.

The LCM of 3 & 4 is 12, so we're using that as the denominator.

The new fractions are 2 4/12 and 1 9/12.

Add 9/12 + 4/12 and you get 13/12, if you simplify its 1 1/12

Now add (2+1) + 1 1/12 and you get the final answer of 4 1/12.
