OpenStudy (studygurl14):

For your first answer, you just need to switch the 3 and 2. The correct answer is 2/3

OpenStudy (fiore01):

OHHH thank you

OpenStudy (studygurl14):

you did the same with #2. You switched the numbers. You put 27:12,but the correct answer is 12:27

OpenStudy (studygurl14):

for 3, the correct one is B

OpenStudy (studygurl14):

for 4, you got the correct rate, but that's not what the question was asking, so you need to take 180 divided by the rate, and that's your answer

OpenStudy (studygurl14):

same with 5. You got it partially correct, but then didn't do the final step of multiplying 10 by 8 to get 80

OpenStudy (fiore01):

So, 1. C 2. D 3. B 4. B 5. A ??
