15/80 can be written as 3/16.
To simplify a fraction, find a common divisor and divide both the top and bottom numbers by it. Continue until there are no more common divisors. For example, 15 and 80 are both divisible by 5. 15 divided by 5 is 3. 80 divided by 5 is 16. So 15 / 80 can be reduced to 3 / 16. No number can divide both 3 and 16 (so they are relatively prime), and thus it cannot be reduced further.
