Answer:
Step-by-step explanation:
Hello, do you agree that for any real number a (different from 0)
[tex]\dfrac{a}{a}=1[/tex]
?
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.
[tex]\dfrac{10}{4}=\dfrac{5*2}{2*2}=\dfrac{5}{2}\cdot \dfrac{2}{2}=\dfrac{5}{2}[/tex]
You just need to be careful with 0, as dividing by 0 is not allowed.
Hope this helps
Thank you.
