In math, is it possible to simplify the fraction 19/20

No, it's not possible. 19 is a prime number, so it's only divisible by 19 and 1. 20 is divisible by 20, 10, 5, 4, 2, and 1. So, it can't be simplified any more.

No. In math, you simplify a fraction by dividing both the numerator and

denominator by their common factor. 19 and 20 don't have any common

factor except ' 1 ', so in math, the fraction is in its simplest form.

You'd have to try some other method, like Biology or Social Studies.
