Answer 3

To add mixed numbers, you need to first convert them to improper fractions, then add the fractions and the whole numbers separately. Let's solve the expression step by step:

1. Convert the mixed numbers to improper fractions:

2 1/5 = (2 * 5 + 1) / 5 = 11 / 5 5 9/14 = (5 * 14 + 9) / 14 = 79 / 14

2. Add the fractions:

11/5 + 79/14

To add fractions with different denominators, you need to find a common denominator. In this case, the least common multiple of 5 and 14 is 70.

Rewrite the fractions with the common denominator:

(11/5) * (14/14) + (79/14) * (5/5) = 154/70 + 395/70

3. Add the fractions with the same denominator:

(154 + 395) / 70 = 549 / 70

4. Simplify the fraction if possible:

549 / 70 = 7 and 49/70

So, the result of the expression 2 1/5 + 5 9/14 is 7 49/70.
