Can you explain how to calculate what percentage increase this is?

If the weight of something increases from 15 grams to 21 grams.



Can someone explain as simply as possible how to calculate the percentage increase?



CheeresCan you explain how to calculate what percentage increase this is?
the amount of the increase over the original x 100.



21-15 = 6. 6/15 = 0.4x100 = 40%
21-15=6

6/15=2/5

2/5x100=40%



Lemon SqeazyCan you explain how to calculate what percentage increase this is?
the increase is 6 grams (21-15)



the increase (6) over the start weight (15) times by 100 is the percentage increase.



so 6/15 *100 = 600/15 = 40.



so the answer is 40%,



dont know where 45% came from
It's the difference (6) divided by the original (15), times 100.



So it's 6/15 (= 0.4)



times 100 (= 40)



40%

((21-15)/15)*100=40%
It's a 40 percent increase.



The equation to calculate this is (y - x) / x where x = starting value and y = ending value. Convert the result to a decimal and multiply by 100 to get the percentage
you just subtract your initial mass from your final mass. You take that difference and divide it by your initial mass.
To convert different values into percentages, just multiply the partial value by 100, then divide that product by the total value.



For example, if you want to know what % of 80 the number 20 is, multiply 20 by 100, then divide the product (2,000) by 80. You'll get 25.
21 - 15 = 6

The weight increases 6 grams.



6/15 = .4

6 grams is 40% of 15 grams



so the weight has increased 40%



when figuring percent increase or percent decrease, divide the amount of change by the starting value (not the end value)
45%
