If a fraction is reduced to an integral, then it is not a fraction
yes
The definition of fraction: 1) it has the form of a / B, 2) both a and B are integers, 3) B contains letters
For example: (X & # 178; - 1) / (x-1) although it is reduced to x + 1, it is an integral
But its (x-1) / (x-1) must be a fraction
