An estimated 333 out of every 252525 men are left-handed.
What percent of men are left-handed?
that would be 0.13%
33300/252525=0.13
you add the two zeroes because it has been multiplied by 100 while 252525 has been multiplied times X then divide and get your answer.
I suspect you meant something else besides 333 and 252525 ....that is not reality....it looks like you typed in too many digits. It is more closely 33/252 = 13 %
