Answer:
7 7/8.
Explanation:
o add mixed numbers like these, we first need to convert them to improper fractions, and then add them. Here are the steps to add 5 3/8 and 2 1/2:
Convert the mixed numbers to improper fractions:
5 3/8 = (5 x 8 + 3)/8 = 43/8
2 1/2 = (2 x 2 + 1)/2 = 5/2
Find a common denominator for the two fractions. The least common multiple of 8 and 2 is 8, so we can convert both fractions to have a denominator of 8:
43/8 + 5/2 = (43/8) + (5/2 x 4/4) = 43/8 + 20/8
Add the two fractions with the same denominator:
43/8 + 20/8 = 63/8
Convert the result back to a mixed number:
63/8 = 7 7/8
