Question

A teacher wants to give 3 markers to

Answer 1

First, find out how many markers in total the teacher will need. 
$25*3=75$
Then, find out how many packages the teacher will need by dividing by 8 because that's how many are in each package.
$\frac{75}{8}=9.375$
Now because there is a remainder of .375 that tells us that there are not enough markers in 9 packages to give all students 3 each.

She will have to buy an additional package to give every student 3 markers each. 

10 Packages are needed.

Answer 2

Teacher wants to give 3 markers to each of 25 students. To find how much markes she need we have to multiply 3*25, so 3*25=75

Finally we can find how many packages she need. To get the answer we have to divide 75 by 8, so
75:8=9.375
Now we have to round up because we cant buy 9.3 packages. The final result its 10.
