Question 940899
To figure the percent divide the portion you have (2) by the total number (40)
and multiply by 100% So:
(portion/total) x 100%=percentage
(2/40) x 100=percentage
0.05 x 100=5%
We are actually finding 1/100 (1%) of the whole and dividing our part to how many 1%s are in it:
{{{portion/(total/100)}}} is equivalent to{{{(portion/total)100}}} 
But the second is easier to use
