**When we have equal numbers or with a common denominator in the numerator and in the denominator, in certain cases,** **we can simplify fractions****.**

**Often we will encounter an algebraic fraction in which the numerator and the denominator can be simplified. For example, this equation:**

### $4\over12x$

is a fraction that we can simplify. The simplification of algebraic fractions is a very important operation that will save us a lot of time when solving exercises and will help us avoid mistakes. In this article, we will learn when it is and is not allowed to simplify the numerator and the denominator.

**Remember!** Simplification between numerator and denominator is possible when the terms involve multiplication operations and there are no additions or subtractions.
