Answer:

28% of 250 is 70

Explanation:

"Percent" or "%" means "out of 100" or "per 100", Let's call the percent we are looking for #p#. Therefore p% can be written as #p/100#.

When dealing with percents the word "of" means "times" or "to multiply".
.
Putting this altogether we can write this equation and solve for #n# while keeping the equation balanced:

#p/100 xx 250 = 70#

#100/250 xx p/100 xx 250 = 100/250 xx 70#

#cancel(100)/cancel(250) xx p/cancel(100) xx cancel(250) = 7000/250#

#p = 28#
