Express percent as decimal: 50% = 50/100 = 0.50 and 80% = 80/100 = .80 so .5o times .80 = .40 = 40%
It is: 40/50 times 100/1 = 80%
It is: 40/50 times 100 = 80%
100*(80 - 50)/50 = 100*30/50 = 60%
There are 100 of them because 50*100 = 5000
40/80 = 40/80 * 100% = 50%
50% of £80 = £40 = 50% * £80 = 50%/100% * £80 = £40
50 from 80 is 100*50/80 = 62.5%
50/80 x 100 = 62.5 Therefore, 50 is 62.5 percent of 80.
80%=80/100 80/100 x 50 questions = 40 correct answers. therefore 50 - 40 = 10 incorrect answers.

% decrease = 60% % decrease = |original value - new value|/original value * 100% = |50 - 80|/731 * 100% = 30/50 * 100% = 0.6 * 100% = 60%
