You move the decimal two places to the left and them multiply

37.26 then divide that by 2=18.63

If you were looking for 15 % you would 10% 37.26 then do half of that18.63 and add them together=55.89

20%=37.26 x 2=74.52

Since I am not very good at math, maybe some of the otherfolks can teach you about percentages in general where you use a formula ….multiply by something divide by some thing else…. I have to rely onthe simle things I know..such as money. I can figure out if 33% percent off makes it a good deal for meHAHA. Best of luck!

372.62/100 = 3.762 x 5 = 18.631

.05 x 372.62 = 18.631

372.62*5=1863.1/100=18.631

18.631 hope that helps

so to get .05 of that # you multiply .05times that number.

best,
