There are two methods: one is to simplify according to the basic properties of the ratio. The method is: multiply the former and the latter by the least common multiple of the denominator at the same time, then convert them into integer ratios, and then simplify them into the simplest ratios. The second method is to simplify the ratio by calculating the ratio. HuàJi?n Interpretation: Generally speaking, it refers to the process of transforming complex formulas into simple formulas in physical chemistry, mathematics and other science and engineering. Fractionation is called reduction for short. Simplification of algebraic expressions includes shifting terms, merging similar terms and removing brackets. Simplified formula is generally the simplest formula, and the number of items is reduced. Solving equations can also be regarded as a simplified process. Simplification can be divided into algebraic expression simplification and fractional simplification. Fractional simplification: one is to simplify according to the basic properties of ratio. The method is: multiply the former and the latter by the least common multiple of the denominator at the same time, then convert them into integer ratios, and then simplify them into the simplest ratios. The second method is to simplify the ratio by calculating the ratio. 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 done research all their lives, and finally they want to simplify.
