87.5%.
The answer is 40%, because one fifth as a percentage is 20%, and if you double 20%, it makes 40%, so to confirm, 2 fifths as a percentage = 40%.Good luck with the rest of your maths!2 fifths = 2 * 1/5 = 2/5∴ 2/5 in percentage = 2/5 * 100 = 40%
90% correct, or 10% wrong.
40%
Expressed as a percentage, 2/5 x 100 = 40 percent. % rate: = 2/5 * 100% = 0.4 * 100% = 40%
2/5 = 40%
percentage = 40%% rate:=2/5 * 100%=200/5= 40%
2-fifths as a percentage = 40%2/5 * 100% = 200%/5 = 40%
5/40 = 0.125 = 12.5%
2/5 = 40/100 40%
2/5 as a percentage = 40%= 2/5 * 100%= 0.4 * 100%= 40%
If five people answer eight questions each, then there are 40 total questions. 5 x 8 = 40 If 12 of those 40 answers are wrong, then 30% of the questions are wrong. This leaves 70% of the questions to be right. 12 / 40 = 0.3 0.3 = 30% 40 - 12 = 28 28 / 40 = 0.7 0.7 = 70%
Two out of 40 is 5%
2 of 5 = 40% wrong .3 of 5 = 60% correct (your score).Please say it was not a math test !
