Answer 1

To find the difference between 13/21 and 6/21, we subtract the numerators (top numbers) and keep the same denominator:

(13/21) - (6/21) = (13-6)/21 = 7/21

We can reduce this fraction to its lowest terms by dividing both the numerator and denominator by their greatest common divisor, which is 7:

7/21 = (7/7) / (21/7) = 1/3

So, the difference between 13/21 and 6/21 is 1/3.
