1. indicates that the band fraction consists of integer and true fraction, and the false fraction is only expressed by an integer fraction.
2. Size relation: the value with fraction is greater than the integer part, and the value with false fraction is less than the integer part.
3. Operation rules: The rules required for mathematical operations with and without scores are different. Addition, subtraction, multiplication, division, etc. , first you need to calculate the integer part, and then you need to calculate the decimal part. However, false scores generally need to be simplified and converted into scores or other forms to facilitate operation and comparison.
4. Application scenario: Scores are often used in daily problems, such as distributing items and measuring length, which is closer to practical application. False fractions are generally used in more complex mathematical calculations and problem solving, such as algebraic operations and equation solving.
Generally speaking, in practical application, the choice of band score and false score depends on specific problems and calculation requirements. Fractions are easier to understand and use intuitively, while false fractions provide greater flexibility and accuracy in complex mathematical operations.
Use scenes with scores and false scores together.
Conversion and comparison of 1. scores: When comparing and sorting scores, it is sometimes necessary to convert band scores and pseudo-scores in order to compare their sizes more intuitively. For example, a band score can be converted into a false score, or a false score can be converted into a band score for size comparison and sorting.
2. Representation of operations and equations: In some complex operations or equations, you can use both fractional and pseudo-fractional to represent the calculation process and results more clearly. For example, in algebraic equations, fractions and pseudo-fractions can be expressed as unknown coefficients or solutions, respectively, for solving and explaining.
3. Decomposition and combination of quantities: In some problems, it is necessary to decompose or combine quantities, which may involve the use of banded points and false points. For example, a certain number of projects are divided into several groups, where each group can be composed of an integer and a true score, and the number of each group can be represented by a band score or a false score.
