how do you tell percentage of change?

Question

Wow, I should know this! First answer wins :)

May Units - 636
June Units - 653

What's the percentage of increase and how do you figure it out?

Answer 1

change = 17
%change = 17/636*100
=2.67%
=3%

Answer 2

subtract the May units from the June units (653-636) then divide the answer( in this case it's 17) you get by the June units(653). After that multiply the answer( 17/653 = 0.0260) which is 0.0260 by 100 and your answer will be 2.6% approximately.

Answer 3

Find the difference (subtract.)
Divide the earlier unit by the difference (division.)
Express as a percent.

653-636=17
17/636 = 0.026729

The percentage of change was a little more than 2.6%.

Answer 4

increase in units = june - may = 653 - 636 = 17

percentage of increase
= increase/initial * 100%
= 17/636 * 100%
= 2.67 %

Answer 5

653-636=17
17/636=0.0267
percent =2.67
june had an increase of 2.67%

Answer 6

653-636= 17
17/653*100=2.6% increase

Answer 7

change = (new - original)

(If positive, it's an increase, if negative, it's a decrease.)

change_as_ratio = change / original
change_as_ratio = (new - original) / original

(Often it is more useful to know by what fraction the amount changed, than to know the absolute number.)

change_% = 100 * change_as_ratio
change_% = 100 * (new - original) / original

(Percent just means "per hundred" so it's 100 times the change represented as a ratio.)

So...

p = 100 * (j - m) / m
p = 100 * (653 - 636) / 636
p = 100 * 0.02673
p = 2.673%

Whether you'd round that as 3%, 2.7%, etc., depends on what your teacher is expecting.

Answer 8

653-636/636=0.02673

636*1.02673=653
