Answer:
The other girl is wrong. I know cuz my teacher told me. She is sooooo close though. The correct answer is 15 over 2, square root 64, 8 1 over 7, 8.14 repeating 14.
Step-by-step explanation:
The first 2 she got right. However, 8 1/7 is 8.142857 repeating which is less than 8.14 cuz 8.14 is 8.141414141414141414... which is greater.
