Answer: 5 5/6
Explanation:
3/4 can be written as 9/12, when we multiply the top and bottom by 3. So 4 and 3/4 is also 4 and 9/12. A double negative = a positive. So 4 9/12 + 1 1/12 is 5 and 10/12. 10/12 can be simplified by dividing the top and bottom by 2, so it equals 5/6. The answer is 5 5/6. With enough practice, you'll be able to do this in seconds.
