The correct answer isn't given for the first problem. 60 out of 1200 is not 60 percent.

Your second and third answers are not correct.

Please try again.

first one:

60/1200 = 0.05 = 5%

You must have a typo in your answer choices.

second one: 800/20000 = .04 = 4% not 4.5%

third one: I got 21 feet 8 inches
