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?

Can you explain HOW you came to the figure of 45%? I want to know how to calculate it, not the answer,
Cheers

the amount of the increase over the original x 100.
21-15 = 6. 6/15 = 0.4x100 = 40%

There was actually a decrease btwn 2006 and 2008 as sales fell by 9300(15000-5700) %decrease = decrement/Original amt x 100% =9300/15000 x 100% =62% decrement btwn 2006 and 2008 However there is a percentage increase btwn 2006 and 2007 which is 13000/15000 x 100% =86.67% Ok if 2008= 57000, increment % = 42000/15000 x100%= 280% 2006 is used as the base value because you are comparing 2008 increment to 2006 sales

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

21-15=6
6/15=2/5
2/5x100=40%

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)

It's the difference (6) divided by the original (15), times 100.
So it's 6/15 (= 0.4)
times 100 (= 40)
40%
That help?

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

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)/15)*100=40%
