0.48 = 12/25
That IS the reduced or simplified fraction.
189 and 40 have no factor in common and so the fraction cannot be reduced.
It is: 2/5 reduced
If the numerator and denominator have any common factors (other than 1), then both the numerator and denominator can be divided by the common factor, and the new fraction will be equivalent to the original fraction in reduced form.
It is: 0.428 = 107/250 reduced
That IS the reduced or simplified fraction.
A fraction and its reduced form are equivalent. The numerator and denominator of the original (non-reduced) fraction will have been divided by their greatest common factor to give the reduced fraction.
189 and 40 have no factor in common and so the fraction cannot be reduced.
It is: 2/5 reduced
If the numerator and denominator have any common factors (other than 1), then both the numerator and denominator can be divided by the common factor, and the new fraction will be equivalent to the original fraction in reduced form.
It is: 0.428 = 107/250 reduced
It is: 0.6 = 3/5
80% = 80/100 which can be reduced to 4/5.
It is a fraction in its reduced or simplest from.
Where the numerator and denominator have no further common factors
These numbers have a common factor of 2 so the fraction can be reduced to 1/5.
For a fraction to be in its simplest form, numerator and denominator must have no common factor.
