B)

d)

9) I'm not really sure how to answer it, but I guess like 2.1, 2.2, 2.5, etc.,
10)


so {5, 6, 7, 8} is the answer
11) for some reason it won't let me insert a picture but put place

above 2, and then place

above 3, and then place

in between 2 and 3, but place it a little closer to three since

12) place

between 2 and three, but closer to two since

and also

and for number 13) the square root of 144 is 12, and the square root of 169 is 13, so any numbers between 12 and 13 will work.
I hope this helped and if not, message me and ill try to explain!
What is her answer? She needs to have an answer. If she doesn't have an answer, then I can't identify the mistake
Answer:
2 2/5
Step-by-step explanation:
Dividing two fractions is the same as multiplying the first fraction by the reciprocal of the second fraction. First convert the first into the improper fraction -8/5. Now because when dividing fractions you keep the first on, change to multiplication and flip the second equation you have
-8/5 x -3/2=?
Now you just multiply across as you would and normal time multiplying fractions. Remember a negative divided by a negative is a positive! And not after you keep, change, flip and multiply you are left with 24/10. Which is equal to 12/5 but you wanted a mixed number so we convert it into 2 2/5
