\(\frac{1}{r}\) of a circular pizza has been eaten. If the rest of the pizza is divided into m equal slices, then each of these slices is what fraction of the whole pizza?
A. \(\frac{r}{rm}\)
B. \(\frac{r-1}{m}\)
C. \(\frac{1}{m}\)
D. \(\frac{m-1}{rm}\)
E. \(\frac{m-r}{rm}\)
Kudos for the right answer and explanation

1/r of the pizza is eaten --> r-1 remains and will be divided into m pieces --> (r-1)/m will be each piece (--> B)

The question is wrong.
(r−1)/rm
is the right answer
1/r eaten, so 1-(1/r) left.
By dividing r-1/r by m we have (r-1)/(rm)
(r−1)/rm
is the right answer
1/r eaten, so 1-(1/r) left.
By dividing r-1/r by m we have (r-1)/(rm)
