Question 1046989: 85% of the cartons of milk on a supermarket shelf had to be removed because they were past their sell-by date.
Of the 240 cartons initially on display,how many remained?

If 85% were removed, 15% remain.
240*0.15=36
10 per cent of anything ending in a 0 is the rest of the number, so 10% of 240 is 24
5% is half of ten percent, and half of 24 is 12.
Therefore, 15% of 240 is 24+12=36.
