LOVE this site, THANK YOU! Anyway, I think there's a Rounding Error for the solution required here. AB=(8.1*2.3)/4.6
Using a calculator I get 4.05 and the exercise requires me to round to 1 decimal place. I tried 4.1 and it didn't work. The answer it wants is 4.0! Thanks for everything though, keep up the GREAT work!!!
