Answer 2

Answer:

The question seems to be about performing arithmetic operations on fractions. Let's break down the question and provide the answers step by step.

Step 1: 21/31 + 14/31

To add these fractions, we simply add the numerators while keeping the denominator the same: 21/31 + 14/31 = (21 + 14)/31 = 35/31.

Step 2: 10 11/19 + 5 14/19

To add these mixed numbers, we first convert them to improper fractions and then add them: 10 11/19 = (10 * 19 + 11)/19 = 201/19 5 14/19 = (5 * 19 + 14)/19 = 109/19 Now, adding the improper fractions: 10 11/19 + 5 14/19 = 201/19 + 109/19 = (201 + 109)/19 = 310/19.

Final Answers:

1. 21/31 + 14/31 = 35/31 2. 10 11/19 + 5 14/19 = 310/19
