An object, a unit of measurement or a whole composed of many objects can be represented by the natural number 1, which is usually called unit "1"
The unit "1" is divided into several parts equally, which means the number of such a part or parts
The unit "1" is divided into several parts equally, and the number of one part is called fractional unit
A fraction whose numerator is smaller than the denominator is called a true fraction; a fraction whose numerator is larger than the denominator or whose numerator is equal to the denominator is called a false fraction
Divisor divided by divisor = divisor of divisor
If you convert a false fraction into an integer, you can convert it into an integer according to the meaning of the fraction, or you can directly calculate the result by dividing the numerator by the denominator
When transforming a false fraction into a fractional one, the numerator is divided by the denominator. The quotient is the integral part of the fraction, and the remainder is the numerator of the fractional part
