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.

(13/21) - (6/21) = 7/21
To simplify this fraction to its lowest terms, we can divide both the numerator and denominator by their greatest common divisor, which in this case is 7.
7/21 divided by 7 = 1/3.
Therefore, the difference between 13/21 and 6/21, reduced to lowest terms, is 1/3.
