(77+83+89+86+x)/5=85 (335+x)/5=85 (335+x)=85*5 335+x=425 x=425-335 x=90 He must get 90% on his fifth test to average 85%.

Oh, dude, so Ravi got 18 out of 20, which is like 90%. And then Karli got 85, which is less than 90. So, like, obviously Ravi's mark was greater. Math doesn't have to be hard, man.
20-3 = 17 and 17/20 = 85/100 = .85 or 85%. Percent is a ratio per cent or 100. Multiplying both the 20 and the 17 by 5 will make the denominator 100 and the percent sought after.
