1. #1 Nope. 5/6 + 2/3 = 5/6 + 4/6 = 9/6
#2 ok
#3 Nope. 9 is a perfect square.
#4 Nope. Suppose x = 1/6. You have 1x/2x
#5 ok
#6 ok
#7 ok
#8 Nope. A has too many -7's
#9 What's the difficulty? Just use the values given:

2s³-4r² if r=1 and s=5
2*5³-4*1²
2*125-4*1
250-4
246

4. Oddly enough, it is C

It should technically be

(-7)x(-7)x(-7)x(-7)x(-7)

But if you change the sign on two of them, the answer is the same, because

(-7)x(-7) = 7x7

5. Here are the answers for number 9 and 10:

1. x = .1515....
2. 100x=15.15.....
3. 100-0.1515... equals 99(do not include the non-terminating numbers, just simplify it to 99)
4. 99x=15(rounded to nearest number)
5. x=15/99=5/33
6. Check it with calculator by dividing 5 by 33

Please put this in your own words :)

10. I would explain to the student that 0.57 can be turned into a fraction that is not improper so it is considered rational.

Please put this in your own words also :)
