Answer 2

Answer:

$-\frac{10}{4}$ = - 2.5

Step-by-step explanation:

First we know :

$\frac{2}{-5} = -\frac{4}{10} = -0.4$

After that :

$\frac{4}{25} = \frac{16}{100} =0.16$

Now we can make an equation :

We want to divide $-\frac{4}{10}$ by something to get $\frac{16}{100}$.

Let's write it in an algebraic way :

1. $-\frac{4}{10}$÷ $x$ = $\frac{16}{100}$
2. Now multiply both sides by $x$.
3. Now we have : $-\frac{4}{10}=\frac{16}{100}x$.
4. Now divide both sides by $\frac{16}{100}$.
5. Now we have : $-\frac{4}{10}$ ÷ $\frac{16}{100}$ = $x$.
6. $x=-\frac{0.25}{0.1}=-\frac{10}{4}=-2.5$
