Ms. Sue can you please check all the answer? I have written them right after every question. Please give me the right answers as well. I might have 2 or 3 questions wrong.
Answered by Ms. Sue
Most of your answers are right. :-)

For 2 and 4, your thinking is correct, but you didn't state the answer correctly.

7, 8, 14, and 24 are wrong.

Ms. Sue I tried a lot for 8. but I have no idea how I can solve this. Please give me exact answer. The rest I think for the 7 the might will be the 445, it is asking for quotient in this. And I made mistake in 24, the questions was asking 16/50.

Please help me with the 8 and 7.
