Answer 2

To solve the expression $\frac{{a + b}}{{b}} \times \frac{{a - b}}{{b}}$ when $\frac{{a + b}}{{b}} = 0.5$, we'll substitute $\frac{{a + b}}{{b}}$ with 0.5 and then simplify the expression.

Given: $\frac{{a + b}}{{b}} = 0.5$

We want to find: $\frac{{a + b}}{{b}} \times \frac{{a - b}}{{b}}$

Substitute $\frac{{a + b}}{{b}}$ with 0.5: $0.5 \times \frac{{a - b}}{{b}}$

Now, simplify: $0.5 \times \frac{{a - b}}{{b}} = \frac{{0.5 \times (a - b)}}{{b}}$

Further simplify: $\frac{{0.5a - 0.5b}}{{b}} = \frac{{a - b}}{{2b}}$

So, $\frac{{a + b}}{{b}} \times \frac{{a - b}}{{b}}$ when $\frac{{a + b}}{{b}} = 0.5$ is $\frac{{a - b}}{{2b}}$.
