Answer:

There were 775 student surveyed.

Explanation:

This question can be rewritten as:

248 is 32% of what?

"Percent" or "%" means "out of 100" or "per 100", Therefore 32% can be written as #32/100#.

When dealing with percents the word "of" means "times" or "to multiply".

Finally, lets call the number we are looking for "n".

Putting this altogether we can write this equation and solve for #n# while keeping the equation balanced:

#248 = 32/100 xx n#

#100/32 xx 248 = 100/32 xx 32/100 xx n#

#24800/32 = cancel(100)/cancel(32) xx cancel(32)/cancel(100) xx n#

#775 = n#
