Answer 2

$\frac{b}{a-b}*(\frac{1}{a}-\frac{1}{b})=\frac{b}{a-b}*\frac{b-a}{ab}=-\frac{1}{a-b}*\frac{a-b}{a}=-\frac{1}{a}$

Answer 3

Calculation of (b/a-b*(1/a-1/b))

To solve the given expression, we can follow these steps:

1. First, simplify the expression inside the parentheses. 2. Then, perform the multiplication and subtraction as per the given expression.

Let's proceed with the calculation.

Simplifying the Expression

The given expression is: b/a-b*(1/a-1/b)

Step 1: Simplify the Expression Inside the Parentheses

The expression inside the parentheses is: 1/a-1/b

Step 2: Perform the Multiplication and Subtraction

Now, we can perform the multiplication and subtraction as per the given expression.

Result

The result of the expression b/a-b*(1/a-1/b) is calculated as follows: - b/a-b*(1/a-1/b) = b/a - b*(1/a-1/b) - = b/a - b*(b-a)/(ab) - = b/a - (b^2 - ab)/(ab) - = (b^2 - ab)/(ab) - (b^2 - ab)/(ab) - = (b^2 - ab - b^2 + ab)/(ab) - = 0/ab - = 0

Therefore, the result of the given expression is 0.

I hope this helps! If you have further questions or need additional assistance, feel free to ask.
