Answer 2

To solve the given expression, we'll perform addition and convert any mixed numbers to improper fractions. Here's the step-by-step calculation:

Step 1: Convert mixed numbers to improper fractions: 9 5/16 = (9 * 16 + 5) / 16 = 149 / 16 1 3/5 = (1 * 5 + 3) / 5 = 8 / 5 2 1/7 = (2 * 7 + 1) / 7 = 15 / 7

11 11/16 = (11 * 16 + 11) / 16 = 187 / 16 1 2/5 = (1 * 5 + 2) / 5 = 7 / 5 5 8/23 = (5 * 23 + 8) / 23 = 123 / 23

Step 2: Add the fractions separately: (149 / 16 + 8 / 5 + 15 / 7) + (187 / 16 + 7 / 5 + 123 / 23)

Step 3: Find a common denominator: The common denominator for 16, 5, and 7 is 560. The common denominator for 16, 5, 23 is 1840.

Step 4: Perform addition: [(149 * 35) / (16 * 35) + (8 * 112) / (5 * 112) + (15 * 80) / (7 * 80)] + [(187 * 115) / (16 * 115) + (7 * 368) / (5 * 368) + (123 * 80) / (23 * 80)]

Simplifying further: (5235 / 560 + 896 / 560 + 1200 / 560) + (21505 / 1840 + 2576 / 1840 + 9840 / 1840)

Step 5: Add the numerators: (5235 + 896 + 1200) / 560 + (21505 + 2576 + 9840) / 1840

Step 6: Simplify: 7331 / 560 + 33921 / 1840

Step 7: Find the common denominator: The common denominator for 560 and 1840 is 322,400.

Step 8: Perform addition: (7331 * 576) / (560 * 576) + (33921 * 140) / (1840 * 140)

Simplifying further: 4,219,856 / 322,400 + 4,748,040 / 322,400

Step 9: Add the numerators: (4,219,856 + 4,748,040) / 322,400

Step 10: Simplify: 8,967,896 / 322,400

Finally, we can simplify the fraction or convert it back to a mixed number: 8,967,896 divided by 322,400 equals 27.8025.

Therefore, the final result is approximately 27.8025.
