The answer to ‘express 1.25 as a fraction’ is 1/8
The first thing you should do in this case is to know how much paper you need to print for the 17 copies.
We have then:
(17) * (130) = 2210
Then, you must calculate the number of reams you need:
n = (2210) / (500) = 4.42
You need 4 full reams and 42% of a fifth ream. So, the cost will be
C = (4.42) * (3.44) = 15.2048 $
The unit cost of each paper is:
Cu = (15.2048) / (2210) = 0.00688 $
answer
the paper is going to cost 0.00688 $ for those reports

Answer:
B)
Step-by-step explanation:
no. of Classes = x
cans = 220
220×x = 220x
no.of classes × cans = total number of cans
Division is basically
x divided by y=x/y so
18 divided by 2/3=
![\frac{18}{ \frac{2}{3} }](https://tex.z-dn.net/?f=%20%5Cfrac%7B18%7D%7B%20%5Cfrac%7B2%7D%7B3%7D%20%7D%20)
we want the bottom number to be =1 so we multiply 2/3 by 3/2 to make it 1 (or 6/6=1), but we have to multiply the top number by 3/2 also so that we don't change the fraction and make our work useless so
![\frac{18}{ \frac{2}{3} } times \frac{ \frac{3}{2} }{ \frac{3}{2} } = \frac{ \frac{54}{2} }{ \frac{6}{6} }= \frac{27}{1}=27](https://tex.z-dn.net/?f=%20%5Cfrac%7B18%7D%7B%20%5Cfrac%7B2%7D%7B3%7D%20%7D%20times%20%20%5Cfrac%7B%20%5Cfrac%7B3%7D%7B2%7D%20%7D%7B%20%5Cfrac%7B3%7D%7B2%7D%20%7D%20%3D%20%5Cfrac%7B%20%5Cfrac%7B54%7D%7B2%7D%20%7D%7B%20%5Cfrac%7B6%7D%7B6%7D%20%7D%3D%20%5Cfrac%7B27%7D%7B1%7D%3D27%20%20)
