The answer would be the second choice, B. 12+15=27.

The answer could not be the first choice, as the difference between 15 and 12 cannot be greater than either of the numbers.
The answer could not be the third choice, as the sum of 27 and 12 should not be less then 27.
The answer could not be the fourth choice, for the same reasoning that I used for the third choice being wrong. The sum of 27 and 15 cannot be smaller than either number.

1). You will have to divide 256/8 because you will need to know how many buses are needed. By dividing these two the total Number of us is needed for a total of 256 people are 32 buses in total.
2). Just divide 350/27 and you will get approximately 13 cupcakes per student. Multiply your answer to 350 divided by 27 by 27 and you will get 324. Then subtract 324 from 350 and you will get 26. So each student receives 12 cupcakes and the teacher receives 26 cupcakes. I’m sorry I’m not that sure but I answered the rest for you
3). Find the common denominator of 2/3 and 1/5 which is 15.
2/3=10/15 and 1/5=3/15
The answer will be 13/15
4). Sane thing for number 4, find a common factor between 8 and 6 which is 24
3/8=9/24
And 5/6=20/24
Add them and you will get 29/24
Since 29/24 is an improper fraction write this improper fraction as a mixed number which will be 1 5/24.
Hope this really helps for your review and good luck! :)
