Answer 2

To add the given mixed numbers, you need to first convert them into improper fractions, then find a common denominator and add the fractions together. Finally, simplify the result if necessary. Let's go through the steps:

Step 1: Convert the mixed numbers to improper fractions: 2 4/7 = (2 * 7 + 4) / 7 = 18/7 1 2/9 = (1 * 9 + 2) / 9 = 11/9 3 4/11 = (3 * 11 + 4) / 11 = 37/11 4 3/7 = (4 * 7 + 3) / 7 = 31/7

Step 2: Find a common denominator: The denominators are 7, 9, and 11. To find a common denominator, we can multiply them together: 7 * 9 * 11 = 693.

Step 3: Rewrite the fractions with the common denominator: 18/7 = (18/7) * (99/99) = 198/63 11/9 = (11/9) * (77/77) = 77/63 37/11 = (37/11) * (63/63) = 259/63 31/7 = (31/7) * (99/99) = 297/63

Step 4: Add the fractions together: 198/63 + 77/63 + 259/63 + 297/63 = (198 + 77 + 259 + 297) / 63 = 831/63

Step 5: Simplify the fraction if possible: 831/63 can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 9. 831/63 = (831/9) / (63/9) = 92/7

Therefore, the sum of the given mixed numbers 2 4/7, 1 2/9, 3 4/11, and 4 3/7 is equal to 92/7.
