Question 15267
Express the fraction 2/5 as a decimal by dividing 5 into 2.00 (you get .40), and then convert the decimal to a percent, by moving the decimal two places to the right.  This means that .40 = 40%.


Another way to do this particular problem is to start with the fraction 2/5 and multiply the numerator and denominator by 2.  This gives the very special fraction 4/10, which as a decimal would be .4 or .40.  Then convert to a percent as above .40 = 40%.
