two pages that are back to back in a text have 201as the sum of their page numbers what are the page numbers.​
REY [17]

Answer:

Pages 100 and 101

Step-by-step explanation:

Round 201 to 200 (to make it easier).

Divide 200 by 2, because it is 2 pages.

You are left with 100.

100 is one of the pages, but because you rounded down 1 number, the other number must be 101, because the pages are back to back.

I hope this made sense, this is just how I figured it out. :)
