the new number divided by the old nuumber e.g If the new price is : £56 and the original price : £80 the percentage depreciation is: 56 / 80 = 0.7 ( the percentage decrease)

percent increase=(new amount-original amount) _____________________ original amount

17

200% increase.-------------------------Actually it is 100%...(new value - original)/original * 100%(8-4)/4 = 1*100% = 100%

Percentage change = (new - original)/original × 100 % = (42.5 - 68)/68 × 100% = -37½ % (Being negative means the change is a reduction.)

% decrease = |original value - new value|/original value * 100%

You can find the percentage of growth between two numbers by using the following equation (New Number - Original Number) Ã· Original Number x 100 New Number: 500 Original Number: 25 500 - 25 = 475 Ã· 25 = 19 x 100 = 1900%. So the percentage of growth from 25 to 500 is 1900%.

You take the original number. You then work out by how much this number has changed (so if the new number is bigger subtract the original number from the new number and if it is smaller subtract the new number from the original). Now you divide the difference (how much the number has changed) by the original number and multiply the result by 100.An example:100 becomes 120.The number has changed by (120 - 100) 20. It has increased by 20.To calculate the percentage change we do:20 (the change) / 100 (the original number) and then multiply by 100 (to turn it in to a percentage rather than a fraction).20/100 * 100 = 20%So, in this example, the number has increased by 20%.

the new number divided by the old nuumber e.g If the new price is : £56 and the original price : £80 the percentage depreciation is: 56 / 80 = 0.7 ( the percentage decrease)

(New amount - Original amt) / Original amount = loss percentage. saurabh K.

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

% increase = |original value - new value| /original value * 100%

Reverse the digits then check of the new number is the same as the original number.

percent increase=(new amount-original amount) _____________________ original amount

You have squared the original number. The original number is now the square of the new quotient.
