if something increases by 15 % to 328 what was the number originally and how do you work this out, thanks
which is 2.852
and then multiply that by 100. which is.... 285.2
these are rounded down, obvs.
im gonna fail bad on this numeracy test
is divide by 1.whatever they ask so, 1.20 for 20%, 1.34 for 34%. to increase by the amount just times it by 1.whatever. Simple really, I think.
a) "the original value" is to taken as 100%
b) the 328 value represents 115%
c) Dividing 328 (i.e. "the 115% value") by 115 gives "the 1% value".
d) To get the original number (i.e. "the 100% number"), multiply "the 1% value" by 100.
you should be a maths teacher
and travel threads
and university threads
and food threads
which is why they're on the social board, I reckon.
