What do we call the process of reducing a fraction to its simplest form?

The process of reducing a fraction to its simplest form is referred to as simplifying a fraction. This involves finding the greatest common divisor (GCD) of the numerator and the denominator, and then dividing both by that GCD. The result is a fraction where the numerator and denominator have no common factors other than one, making it the simplest, most reduced form. This is important because it allows for easier calculations and better understanding of the fraction's value.

The other terms listed do not accurately describe the process of reducing fractions. Normalizing a fraction typically refers to adjusting fractions to a common denominator or scale, which is different from simplifying. Evaluating a fraction generally means calculating its numerical value (e.g., converting it to a decimal), and calculating the fraction may imply performing arithmetic operations involving the fraction, which is not the same as reducing it.
