Sixty-five percent of the 8th grade class is selling magazines for the class fundraiser. If 195 students are selling magazines,
kari74 [83]

Answer:

300 students

Step-by-step explanation:

If 195 students is 65%, then we can divide 195 by 65 to find what 1% is.

195/65= 3

So 1% of the 8th grade class is 3 students. We want to know how many students are in the whole class, which would be 100% of the class.

If we multiply the 3 (which is 1%) by 100 (to get 100%) we can find the total number of students.

3x100=300

We can check this by finding 65% of 300, and seeing if that is 195.

300x.65=195

It does check out.
