To change 4% into a decimal, move the decimal point left 2 (or divide by 100):
so, 9.22 * .04 = .3688
Also, to go from decimal to percent, move decimal point right 2 (or multiply by 100):
.15 = 15%
as 100% means 100 units. 4% means 4 out of a 100 units, which can be expressed in the fraction form as 4/100.
9.22 X 4/100
alternatively, you could also express it as 0.04 in decimal form.
just go Times 4, then slide the decimal point over
if you are doing it in your head? an easy way to go times 4, is to double the number and then double it again
so double is 18.44
& double again is 36.88
then slide your decimal two places left, voila, 0.3688
(if you are doing significant figures like in Science, round this to 0.37 because you only get two digits as significant figures)
4% is .04 so 9.22 x .04 you can do on a calculator or if your doing it by hand, just multiply 922 by 4 and move the decimal point left 4 numbers which is .3688
