Simplifying the expression:
A/1 - b + a - ab / b - 1 b + 1 / a= (A - b + a - ab) / (b - 1) b + 1 / a= (A - ab + a - b) / (b - 1) * b + 1 / a
Therefore, the simplified expression is: (A - ab + a - b) / (b - 1) * b + 1 / a
Simplifying the expression:
A/1 - b + a - ab / b - 1 b + 1 / a
= (A - b + a - ab) / (b - 1) b + 1 / a
= (A - ab + a - b) / (b - 1) * b + 1 / a
Therefore, the simplified expression is: (A - ab + a - b) / (b - 1) * b + 1 / a
