#22.7%# decrease

Any percentage change (whether an increase, decrease, profit, loss, discount, mark-up etc) can be calculated using the same method.

#% "change" = "amount of change"/"original amount" xx 100%#

The number of pupils dropped from 1312 to 1014.

The change = #1312-1014 = 298#

#298/1312 xx100%#

=#22.7%# decrease
