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
I think you subtract the new amount from the original amount and then move the decimal over twice to the right of the number and that's your percent. :)
percent of increase = (new amount - original amount)/original amount p = (35 - 25)/25 p = 10/25 = 2/5 p = 0.4 p = 40%
You multiply the percent ( so 40% = .4) by the number then add the product to the original number.
Original price - discount = new price Original price - (Original price x 0.15) = 18.00 Which can be written as: 1 Original price - 0.15 Original price = 18.00 Which can be written as: 0.85 Original price = 18.00 Wich can be written as: Original price = 18.00 / 0.85 Original price = 21.18 Note that since there is 15% off in the original price, the new price is essentially (100% - 15%) = 85% of the original price.
3:2
new amount minus original amount over original amount
I think you subtract the new amount from the original amount and then move the decimal over twice to the right of the number and that's your percent. :)
When the new amount is less than the original amount, the percent of change is negative. This indicates a decrease, which is calculated by taking the difference between the original amount and the new amount, dividing it by the original amount, and then multiplying by 100 to express it as a percentage. For example, if the original amount is 100 and the new amount is 80, the percent change would be -20%.
20 to 30 is a 50% increase.
Percent Decrease = (Original Amount - New Amount)/(Original Amount) * 100% The percent decrease from 220 to 33 is 85%
Percent Increase= (New Amount - Original Amount)/Original AmountExample:New amount: 200Original amount:5(200 - 5)/5(195)/5 = 39% increasePercent Decrease = ? Someone edit this part ;)
percent increase=(new amount-original amount) _____________________ original amount
200%
Percent change can be found using the formula below:(new amount) - (original amount)% change = __________________________(original amount)Using this formula, we find that2.8 - 3.5 -0.7_______ = ____ = -0.2, which equals a 20% decrease (negative answer)3.5 3.5
28.57% decrease.
%=New amount-original amount/original amount X 100 ex: New amount=200 original amount=120 200-120=80 80/200=.4 X 100=40 but it just tells you to round to the nearest tenth most of the time so its 40 answer=40
(New amount - Original amt) / Original amount = loss percentage. saurabh K.
