let it be x%.
from definition of percentage whenever we calculate % it is something divided by 100.
so x% is x/100.
(x/100) of 400 is 320. this can be written mathematically as
(x/100)*400 = 320 or x=320*100/ 400;
or x=80 . thus 80% of 400 is 320.

Calculate 320*100%/400. Simplify, then work out what you have left. (the 100/400 reduces to 1/4, so just divide 320 by 4 to get your answer)
