90% increase
the percent change is how much something has increased or decreased by in percentage. e.g: 2 --> 3 is a 50% change because it has changed by 1 and 1 is 50% of 2
One half of something is 50 percent (50%).
If you have 70% of something and 30% of another identical "something" that is equivalent to 50% of the two "somethings".
50% increase
The change is +50%.
50% = 50/100 = 0.5
A 50 percent decrease.
Percentage change = 100*(41-50)/50 = 100*(-9)/50 = = -18%
Find 10% then times the 10% by 3 (to find 10% divide something by 10)
70%
-30%
