Answer:
6 6/8, simplified to 6 3/4
Explanation:
First, add the whole numbers. 2+4 = 6. Next, add the fractions. In this example the denominators are the same so you simply add the numerators (when summing two fractions you don't add the denominators). So 5/8 + 1/8 = 6/8, which you can simplify to 3/4. Add the 6 from the first step to that, and you get 6 3/4
