Answer:
\(\frac{1}{4}\)

Explanation:
A fraction in the simplest form is a fraction in which there are no common divisors between the numerator and the denominator.

The given fraction is 
\(\frac{25}{100}\)

We can note that both the numerator and the denominator can be divided by 5. Doing this, we will get:
\(\frac{5}{20}\)

Again, we can note that both the numerator and the denominator can again be divided by 5.
This will give us:
\(\frac{1}{4}\)

The reached fraction 
\(\frac{1}{4}\) has no common divisors between the numerator and the denominator. Therefore, it is in the simplest form.

Hope this helps :)
