<h3>Answer:</h3>
10 2/3 + 3/4 = 11 5/12
<h3>Explanation:</h3>
Let's add the fractional parts to start with.
... 2/3 = 8/12
... 3/4 = 9/12
Then ...
... 2/3 + 3/4 = 8/12 + 9/12
... = (8+9)/12 = 17/12
... = (12/12) + (5/12) = 1 5/12
Adding the integer part to that, we get
... 10 + 1 5/12 = 11 5/12

Subtracting is the same as adding the opposite. So, subtracting a negative is the same as adding a positive. Any even number of minus signs becomes a plus sign when adding like this, or when multiplying or dividing.
