seven and 4 fifths

Two and three-eighths plus one and seven-eighths equals four and two-eighths, which can be to four and one-fourth. Here's how to find the answer. First, you add the two whole numbers together, giving you three. Next, since you are adding two fractions with the same denominator, you add the numerators together, which gives you ten eighths. You then convert that to one and two eighths and add the one to three which is four. Finally, you divide both the numerator and the denominator by two. The final answer is four and one-fourth.
