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.
80% = 80/100 which can be reduced to 4/5.
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.
80% = 80/100 which can be reduced to 4/5.
0.48 = 12/25
It is: 0.428 = 107/250 reduced
It is a fraction in its reduced or simplest from.
6 percent is .06 or 6/100, or reduced 3/50.
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.
