To write the decimal expression in its simplest form, we need to write the decimal into a fraction:
Then, we need to simplify the fraction, using common divisors for the numerator and the denominator of the fraction:
Therefore, since 14 and 25 do not have common factors, then the simplest form of the fraction is 14/25.
56 and 100 have common factors: 2 and 2. That is why we obtain 28 and 14 for the numerator (we divide 56 by 2, and 28 by 2), and we follow a similar procedure in the denominator.
