Reduced fraction

Step-by-step explanation:

One can always multiply numerator and denominator by the same number in order to find equivalent fractions. By in the case in which only multiplication (and not cancelling common factors) will help find an equivalent fraction, si when we are dealing with an already reduced fraction.

For example:

1/3 (one third), we can multiply numerator and denominator by a factor of 2 and get the equivalent fraction 2/6 as shown below:

but one cannot reduced the fraction 1/3 any further because it is already a reduced fraction.

answer: c
