Question

A-b/b-a = чему равна дробь

Answer 1

A-b/b-a = - (b-a)/b-a = -1

Answer 2

To evaluate the expression A-b/b-a, we need more information about the values of A and b. As it stands, the expression cannot be simplified without knowing the specific values of A and b.

If A and b are constants or known variables, you can substitute their values into the expression and then perform the arithmetic operations to find the result.

For example, if A = 5 and b = 2, then:

A - b = 5 - 2 = 3 b - a = 2 - 5 = -3

Now, the expression becomes:

(5 - 2) / (2 - 5) = 3 / -3 = -1

So, if A = 5 and b = 2, the fraction evaluates to -1. However, keep in mind that the value of the fraction will change depending on the specific values of A and b.
