Ok so the correct answers are both A. and B.

It would be A. between 1.5 and 2, because the number 1.77 is in between those two numbers. It is greater than 1.5 but also less than 2.

It would be B. to the right of 1.71, because the number 1.77 is greater than 1.71.

I hope this helps! Good luck on your homework!!
