It is simple.
125%=125/100
Just multiply 160 by the inverse of 125/100 and u get ur answer
It is 160*100/125=128

last yr attendance * (125 /100) = this years'
last yr att. = (this years * 100 ) / 125
= (160 * 100 ) / 125
= 128

Let last yrs attendance = x
then:
This yrs att = Last yrs att * % increase
125% = 1.25 when written as a decimal
so:
160 = x * 1.25
therefore:
160 / 1.25 = x
and:
x = 128

1.25 x = 160
x = 160 / 1.25
x = 128

you take 1.25 that's 125%
and dived that into 160
you get 128
that's your answer
