You know that the original number (call it 'N') was increased 15%.
N plus 15% of N = 230
1 N + 0.15 N = 230
1.15 N = 230
Divide each side by 1.15 :
N = 230 / 1.15
N = 200
Divide (the known part) by (the percent). The quotient is the whole unknown number.
The number is unknown.
4.5 percent of the original number.
Any number as a percent is 100 times the original number, in this instance, 9.5 %
175 is the original number.
The result is the knowledge of another number that is equal to that percent of the original number,
30 / 0.08 = 375 Therefore, the original number is 375.
Divide the number by 20 to find 1% and times this by 100 to give 100%
First you subtract the new number from the original number then divide it by the original number and multiply that by 100 original-new __________*100 original
Multiply the original number by 0.95
The easiest way is to multiply the original number by 1.08. Otherwise, multiply the original number by .08 and add the resulting number to the original number.
Multiply the number by the percent in decimal form, and subtract the result from the original number. Alternatively, multiply the number by (1 - the percent).
