Answer 2

It looks like you've performed a series of calculations to simplify the expression:

$-\frac{250}{400} : \left(-\frac{25}{20}\right) = \frac{250}{400} \times \frac{20}{25} = \frac{10}{20}$

However, there seems to be a small mistake in your calculations. Let's go through it step by step:

1. $-\frac{250}{400} : \left(-\frac{25}{20}\right)$ means dividing $-\frac{250}{400}$ by $-\frac{25}{20}$.

2. When you divide by a negative number, it's the same as multiplying by its reciprocal. So, $-\frac{250}{400} : \left(-\frac{25}{20}\right)$ becomes $-\frac{250}{400} \times -\frac{20}{25}$.

3. Now, let's simplify the fractions:

   $-\frac{250}{400} \times -\frac{20}{25} = \frac{5}{8} \times \frac{4}{5} = \frac{5 \times 4}{8 \times 5} = \frac{20}{40}$.

So, the correct simplified result is $\frac{20}{40}$, which can be further reduced to $\frac{1}{2}$, not $\frac{10}{20}$.
