Answer:
The correct quotient is 3.
I think Derek has mistaken to divide [tex]-\frac{2}{21}[/tex] by [tex]\frac{2}{7}[/tex].
Step-by-step explanation:
We have to check the quotient of [tex](-\frac{2}{7}) \textrm{ divided by }(-\frac{2}{21})[/tex].
Part A:
Now, [tex](-\frac{2}{7}) \textrm{ divided by }(-\frac{2}{21})[/tex].
= [tex]\frac{-\frac{2}{7} }{-\frac{2}{21} } =3[/tex]
So, the correct quotient is 3.
Part B:
Derek says that the quotient is [tex]-\frac{1}{3}[/tex].
So, I think Derek has mistaken to divide [tex]-\frac{2}{21}[/tex] by [tex]\frac{2}{7}[/tex]. (Answer)
