Answer:
The Option A is correct.i.e., [tex]-40\frac{1}{4}[/tex]
Step-by-step explanation:
Given: Length of thread a student cuts = [tex]5\frac{3}{4}[/tex] inches
total no. of student that cut thread = 7
To find: Number which represent change in amount of thread on spool.
Length of thread a student cuts = [tex]5\frac{3}{4}[/tex]
= [tex]\frac{4\times5+3}{4}[/tex]
= [tex]\frac{23}{4}[/tex] inches
Length of thread 7 student cuts = [tex]\frac{23}{4}\times7[/tex]
= [tex]\frac{161}{4}[/tex]
= [tex]40\frac{1}{4}[/tex] inches (Coverting into mixed fraction)
So, negative of length that 7 student cut from spool is the number represent change in amount of thread.
Therefore, The Option A is correct.i.e., [tex]-40\frac{1}{4}[/tex]
