If you restated the question to be in the form of what is the % of what, you would be able to set up the formula is over of equals percent over 100.
is/of = %/100
This will allow you to figure out any problem, no matter which part is missing.
16 = your what is
80 = your of what
_x_ = your percent (since that is the part you don't know)
100 goes in the same place every time.
so:
16/80 = x/100
cross multiply --> 80x = 1600
divide both sides by 80 --> x = 1600/80
so, x = 20
so, 16 is 20% of 80
