When the numerator and denominator of a fraction have no non-zero common factor, the fraction is called the simplest fraction. Just like fractions can't be simplified, it's called simplest fraction. The process of reducing the same factor in a score is called reduction. If there is no reducible factor in a score, it is simplest fraction. The process of reducing the common factor of the numerator and denominator of a fraction is called fractional reduction.

The introduction significance of fractional simplification: generally refers to the process of transforming complex formulas into simple formulas in physics, chemistry, mathematics and other science and engineering, and fractional simplification is abbreviated as simplification.

Significance: Simplification is a very important concept in mathematics. A complex formula must be simplified to find its value simply. Many mathematicians in history have studied for simplification all their lives. For example, elimination and reduction proposed by mathematicians in Central Asia are also aimed at simplifying equations.
