There are 12 students in a class that represent 40 percent of the class. I'm trying to figure out how many students there are for 20%, 60%, 80%, and 100% of the class. PLEASE HELP IM IN A TEST

A multiple of  

5

Explanation:

Percent means "per hundred", expressing a proportion.

The proportion of boys in the class is:

40

100

=

2

⋅

20

5

⋅

20

=

2

5

In other words, for every  

5

students in the class,  

2

are boys and  

3

are girls.

In order that the figure  

40

%

be exact, the number of students must be a multiple of  

5

.

Then the number of boys will be the corresponding multiple of  

2

and the number of girls the corresponding multiple of  

3

.

That is about as much as we can deduce from the question as given.
