i was taught to do: is. %
--- = ---
of. 100
so in your case your equation would look like x. 200
---- = ------
47. 100
so you cross multiply 200 and 47 and get 9400.
then cross multiply 100 and x and you get 100x.
now you divide 9400 by 100 and get 94.
so the answer is x=94 but for some reason this equation wasnt written correctly
