That doesn't even make sense if you think about it. The number is going to have to be higher because 216 is only 32% @mathkid911

just remember that the word is is = and of is multiply. so from the word equation 216=.32x (put the percent into a decimal). Solve for x by dividing 216 by .32 and you get your answer.

anonymous · Answer

So 32% of what is 216... 
change percent to decimal : 32% = 32/100 = 0.32 
" of " means multiply 
" what number " we will call x 
" is " means = 

0.32 (x) = 216 -- divide both sides by 0.32 
0.32x/0.32 = 216/0.32 
x = 675 

check... 
32% of 675 = 216 
0.32(675) = 216 
216 = 216 (correct)
