Which number does not have the same value as 15%? F. 3/20 G. 0.15 H.15/100 J. 0.015

OpenStudy (anonymous):

15% as a decimal is .15. So finding the one that isn't equal to .15 is your answer.

OpenStudy (anonymous):

which of the following numbers is greater than 2 1/4 but less than 2 3/4? A. 2.82 B. 2.70 C. 2.25 D. 2.15

OpenStudy (anonymous):

Since your options are all decimals, you just have to covert your mix numbers into decimals. 2 1/4 is 2.25 and 2 3/4 is 2.75. So any numbers that fall between those two number are your answer.

Mr. Cafe's sixth grade class voted on when to have their class party. One third of the class voted for valentine's day. fifteen students voted for MLK day. the remaining 3 students voted for thanksgiving day. How many students voted?

OpenStudy (anonymous):

??

OpenStudy (anonymous):

Oh oh, okay, so you know that there is at least 18 students. Now finding out what that one third goes like this, and I'll try my best to explain it. 18 students equals 2/3, so (18/2) * 3 is your answer as to how many students in the class, which would be 27.

OpenStudy (anonymous):

27 students?

OpenStudy (anonymous):

correct?

OpenStudy (anonymous):

Yup.
