Answer 3

To solve the expressions, let's take one step at a time:

1. Calculate 5/9 ÷ 3/5: To divide fractions, you can multiply the first fraction by the reciprocal of the second fraction. (5/9) ÷ (3/5) = (5/9) * (5/3) = 25/27

2. Calculate 3/8 ÷ 3/5: Similar to the previous step: (3/8) ÷ (3/5) = (3/8) * (5/3) = 15/24 = 5/8

3. Calculate 2 3/11 * 7/9: Convert the mixed number to an improper fraction: 2 3/11 = (2 * 11 + 3)/11 = 25/11 (2 3/11) * (7/9) = (25/11) * (7/9) = 175/99

4. Calculate 6 8/11 ÷ 1 2/7: Convert both mixed numbers to improper fractions: 6 8/11 = (6 * 11 + 8)/11 = 74/11 1 2/7 = (1 * 7 + 2)/7 = 9/7 (6 8/11) ÷ (1 2/7) = (74/11) ÷ (9/7) To divide fractions, multiply the first fraction by the reciprocal of the second fraction. (74/11) * (7/9) = 518/99

5. Calculate 518/99 - 1 1/8: Convert the mixed number to an improper fraction: 1 1/8 = (1 * 8 + 1)/8 = 9/8 (518/99) - (9/8) To subtract fractions, they must have the same denominator, so we need to find a common denominator. The common denominator for 99 and 8 is 792. (518/99) = (518/99) * (8/8) = 4144/792 (9/8) = (9/8) * (99/99) = 891/792 Now, we can subtract: (4144/792) - (891/792) = 3253/792

So, the final result is: 25/27, 5/8, 175/99, 518/99, 3253/792
