Question

Answer 1

30

Step-by-step explanation:

To know how many rolls could be made, we need to divide 3 3/4 by 1/8.

So, first, let's convert the mixed number 3 3/4 to a fraction

`3(3)/(4)=((3*4)+3)/(4)=(12+3)/(4)=(15)/(4)`

Now, we can divide 15/4 by 1/8

`(15)/(4)/(1)/(8)=(15)/(4)*(8)/(1)=(15*8)/(4*1)=(120)/(4)=30`

Therefore, the answer is 30.
