How do I calculate percentage change?

I have two numbers, for example 0.14 and 0.17. These two numbers represent an increase. I want to know what the percentage change is. The difference (0.03) is what percentage of 0.14?

How does one calculate this? Thanks.How do I calculate percentage change?
percentage change is your difference over the original number multiplied by 100
((.17 - .14)/.14) * 100 = (.03/.14) * 100 = (3/14) * 100 = (300/14) = (150/7) = about 21.4% increase.How do I calculate percentage change?
Okay, you have one number (we'll say 50) and you want to find out what percentage another number (say 10) is of it?



10/50 = 0.2

0.2 x 100 = 20%
work out the difference between the original and new value

divide the difference by the original value

multiply by 100

% change = [diff / original] x 100



With a change of 2 -%26gt; 5 it will be



[3 / 2] x 100 = 150% changeHow do I calculate percentage change?
Let 0.3 be (X % change of 0.14)

Therefore 0.3=X% of 0.14

3/10 = X/100 * 14/100

X=214.286 or 30/0.14
