R wants to round 47 to the nearest ten. Which halfway number can help him? 45, because it is halfway b/w 40 & 50 or 50, because it is halfway b/w 0 & 100?

You need to round 47 to the nearest 10.

Which number is closest to 47?

20, 30, 40, 50, 60, 70

As you can see, 47 is closest to 50.

the answer would be 50 because if he wants to be rounding to the nearest 10 then that's what it would be

Best explanation I can come up with is:

45 B is the correct answer. Raphel wants to round to the nearest 10. Which would be 50. In normal rounding techniques the 47 would round up, but in this case, you have to look at it as what can replace 47 with the halfway number to round to the nearest 10. Replace 47 with 45 and your nearest rounding number is 50! Goes against everything I learned in math!
