How do i write a fraction in the simplest form

Ask if the numerator and denominator can be divided by the same number, which is called a common factor.

See if at least one number in the fraction is a prime number.

Simply just find the least common factor between the numerator and the denominator of the fraction, For example, 2/4, you know that between the two numbers, they both share the same common factor,  2, so divide 2 on the top and the bottom, and then your final  answer would be 1/2. However, if there seems to be no common factor between the numerator and the denominator for a fraction, do not simplify it any more. You cannot have a decimal as a numerator or a denominator. For example,  3/5 has no common factor so you do not have to simplify it as it is already at its most simplest form.
