Seven students cut 5 3/4 inches of thread from a spool for a school project. what number represents the change in the amount of the thread on the spool?
a.) -40 1/4
b.) -35 3/4
c.) -29 3/4
d.) -26 1/4

Step-by-step explanation:

Number of students in the school project = 7

So, total part which is cut from the thread on the spool = Number of students × Part of the thread cut by one student

But, we are asked to tell a number which represents the change in the amount of the thread on the spool.

⇒ Required Number = Inverse of the total part which is cut

i think c. but don't trust it.
