When you are ask what is the percent 150 of 40, you have to think about math. The answer to that math question is six thousand you have to times one hundred by forty.

Divide it. Say you have 20 and want to know what percent of 100 20 is. 20/100= .20 (20 percent) (read percent as parts of 100) You have 100 and you want to know what 40 percent of 100 is? 100 x .40 = 40

The percentage of 2/5 is 40%. The word 'percent' mean 'per hundred'. So you multiply the five by whatever it takes to make 100, in this case 20. Then multiply the 2 by 20 as well and you get 40. So the answer is 40 per cent. It is: 2/5 times 100 = 40%
