First, simplify the score to the simplest form.
First of all, we need to simplify the fraction to the simplest form, that is, the numerator and denominator have no common factor. This can be achieved by finding the greatest common divisor of numerator and denominator, and then dividing both numerator and denominator by the greatest common divisor. For example, for the fraction of 18/24, the greatest common divisor is 6, and the numerator and denominator are divided by 6 at the same time to get the simplest form of the fraction of 3/4.
Second, divide the numerator by the denominator.
Next, we need to divide the numerator by the denominator to get the integer part and the remainder part. For example, for a score of 3/4, we can calculate as follows:
3 ÷ 4 = 0 ...3
That is to say, when the numerator 3 is divided by the denominator 4, the quotient is 0 and the remainder is 3. This remainder represents the fractional part of the fraction and is needed in the process of integer conversion.
Third, determine the integer part and band fraction.
According to the calculation results of the previous step, we can get the integer part and the band fraction. If the remainder is 0, the fraction is already an integer, and the integer part is the quotient; If the remainder is not 0, the integer part and the remainder part can be combined into decimal form. For example, for a score of 3/4, we have the following two methods to round it off:
The integer part is 0 and the fraction is 3/4.
The integer part is 0, the remainder is 3, and the fraction is 0 3/4.
For the second method, the integer part is 0 and the remainder is 3, that is to say, the fractional part is 3/4, that is, 0.75, and the fractional part can be written in decimal form, that is, 0 3/4.
Fourth, the application of integers
Fractional integers are widely used in life and study. For example, in daily life, we need to change time into hours and minutes, which involves the problem of fractional integers; In mathematics learning, rounding is the premise of fractional addition, subtraction, multiplication and division, size comparison and other operations, and also the basis of solving equations, taking derivatives and other advanced mathematics knowledge.
Rounding is also an important test center in mathematics competition, which requires candidates to master the methods and skills of rounding. For example, rounding can be used to solve some practical problems about fractions, such as finding proportion, average and sum. To solve these problems, it is necessary to turn fractions into integers or fractions, and then carry out corresponding operations. Therefore, mastering the method and application of integers is one of the keys to improve mathematics level and competition results.
In short, fractional integer is the process of converting fractions into integers or fractions. Fractions need to be reduced to the simplest form, and then the numerator is divided by the denominator to get the integer part and the remainder part, and finally the rounding result is obtained by combination. Integer is widely used in life and study, and it is the basis of mathematical operation and solving practical problems.
