Answer:

Step-by-step explanation:

Hello, do you agree that for any real number a (different from 0)

\dfrac{a}{a}=1

?

5/5 = 1 for instance.

So, when you have the same common factor at the numerator and at the denominator you can eliminate it. For instance.

\dfrac{10}{4}=\dfrac{5*2}{2*2}=\dfrac{5}{2}\cdot \dfrac{2}{2}=\dfrac{5}{2}

You just need to be careful with 0, as dividing by 0 is not allowed.

Hope this helps

Thank you.
