Scores are divided into two categories: true scores and false scores. There are two kinds of false scores.
(1) False fraction, if the numerator is not divisible by the denominator, can be written as a fraction. For example:
(2) a false fraction can be written as a natural number if the numerator is divisible by the denominator. For example:
In essence, the band soundtrack is not a kind of soundtrack, but a form of false soundtrack.
Extended data:
Use fractions to calculate addition and subtraction, and the integer part and the fraction part should be added and subtracted separately. If the reduced score is less than the reduced score, 1 should be taken from the reduced integer part to become a false score, and then combined with the original reduced score and subtracted.
When calculating multiplication and division with fractions, it needs to be converted into false fractions to calculate.
note:
1. Scores with scores cannot be false scores.
2. When the band score is multiplied by letters, it should be written as a false score.
Algebra, generally don't have to take a fraction, just use a fake fraction. Therefore, it is relatively rare to get scores.
No matter what input method is used, scoring on Baidu is easy to be confused. For example, three and a fifth. You can make it clear by entering 3+ 1/5, but you can't enter 3 1/5 or 3* 1/5.
