To solve this problem, the easiest way is to first add the whole numbers and then add the fractions. After that, we can further simplify the number.
2 3/4 + 4 3/4
First we add the whole numbers.
2 + 4 = 6.
Next, we add the fractions.
3/4 + 3/4 = 6/4.
So, your answer is 6 6/4.
However, this answer is not in simplest mixed-number form, because 6/4 is more than one, or an improper fraction.
6 6/4 = 7 2/4
However, 2/4 isn't in simplest form.
7 2/4 = 7 1/2
So,
2 3/4 + 4 3/4 = 7 1/2
