Addition is the most basic method in fractional operation. For example:1/3+2/3 = (1+2)/3 = 3/3 =1. Subtraction is to subtract a fraction. Note that numerator and denominator should be calculated separately. Multiplication is to multiply the numerator and denominator of the fraction to get the result, and then simplify the fraction. The division operation is to divide one fraction by another, that is, the numerator of the first fraction is multiplied by the denominator of the second fraction, and the denominator is divided by the numerator to get the result.
Fractions are widely used. For example, in daily life, we often need to use scores to calculate the ingredients of recipes or calculate discounts when shopping. In industrial production, scores can be used to calculate specific gravity, size and so on. In scientific research, scores can be applied to statistical analysis, probability calculation, proportional relationship and so on. Therefore, it is very important to master the method of fractional operation, which will help us to better apply mathematical knowledge to various fields.
