Then add the numerators.

been working on this for a while....have no idea

You can start with the multiples of the larger denominator.

21, 42, 63, 84, 105

Which of those above numbers is evenly divisible by 14?

To add fractions, you need to have a common denominator. Here's how you can find the sum of the fractions 8/21 and 3/14:

Step 1: Find the least common multiple (LCM) of the denominators, which in this case is 42.

Step 2: Convert the fractions to have the same denominator. To do this, multiply the numerator and denominator of the first fraction (8/21) by 2, and multiply the numerator and denominator of the second fraction (3/14) by 3. This gives us:

(8/21) x (2/2) = 16/42
(3/14) x (3/3) = 9/42

Now, both fractions have a denominator of 42.

Step 3: Add the numerators together. 16/42 + 9/42 = 25/42

Therefore, the sum of 8/21 and 3/14 is 25/42.
