Multiply like you did with the calculator. You don’t have to add or subtract
.40 x 225 = 90.

40% of 225 is 90

the answer of 90 is correct. to get it, take 10% of 225 = 22.5 then multiply that by 4 (22.5 x 4 = 90) or easier, multiply by 2 (22.5 x 2 = 45) then again by 2 (45 x 2 = 90).

40% of 225 is….
225/100=2.25
2.25*40=90
your confusing your self by saying subtract or add
if you want to find a percentage of something then, divide by 100, times by the percentage your finding e.g. 12% of 500
500/100=5
5*12=60
hope this helps
they way you done works too =D
my mum was fighting with me when i done that because she thought i was wrong.
