For example, 4/2 is a false fraction, 4 is a numerator, 2 is a denominator, and the value of 4/2 is equal to the value of 4 divided by 2, which can be divisible, and the quotient obtained is 2, which is an integer; 5/2 is also a false fraction, 5 is a numerator, 2 is a denominator, and 5 is not divisible by 2, so there is a remainder, so a fraction is formed. The quotient is 2, the remainder is 1, the integer part with fraction is 2, and the numerator is 1. The result is 2 and12.
