One year, the population of a city was 352,000. Several years later it was 337,920.

kvasek [131]

hi

here is the method :

you take Value 1 and Value 2

And you do : ( Value 2 - Value 1) / (Value 1 ) * 100

Here we have : Value 1 = 352 000

Value 2 = 337 920

So now we apply :

( 337 920 - 352 000 ) / ( 352 000) * 100 = -4

Population decreased by by 4 %

You can also make :

352 000 * X = 337 920

X = 337 920 / 352 000

X = 0.96

if the multiplier is 0.96 , it's mean that we lost 1 -0.96 = 0.04

which mean - 4%
