So, what is the total lenght of the pieces that wer cut off?
we multiply the lenght by the number:
4

*5=20+

=21

and we subtract this from the original pipe, that is
30

-21

we need to bring the two fractions to the same denominator (by multiplying the fraction art in the first by 3 and 4 the second):
30

-21

=9

so the correct answer is D!
