Answer 3

To add the fractions 5 5/9, 4 7/9, 3 20/21, and 16/21 together, you can follow these steps:

Step 1: Add the whole numbers separately. 5 + 4 + 3 + 0 = 12

Step 2: Add the fractions separately, making sure the denominators are the same (which in this case is 9).

5/9 + 7/9 + 20/21 + 16/21

Step 3: Find a common denominator for 9 and 21, which is 63. Then, convert all fractions to have a denominator of 63.

(5/9) * (7/7) = 35/63 (7/9) * (7/7) = 49/63 (20/21) * (3/3) = 60/63 (16/21) * (3/3) = 48/63

Step 4: Add the fractions with the common denominator of 63.

35/63 + 49/63 + 60/63 + 48/63 = (35 + 49 + 60 + 48) / 63 = 192/63

Step 5: Simplify the fraction if needed. In this case, you can simplify it by dividing both the numerator and denominator by their greatest common divisor (which is 3).

(192/3) / (63/3) = 64/21

So, the sum of 5 5/9, 4 7/9, 3 20/21, and 16/21 is equal to 64/21.
