This is a quadrilateral, and by definition, the sum of all the interior angles is 360. So, we can just sum up all the expressions and set them equal to 360:
Well,5/6 is closer to one than 5/8 is,just add 1/6+5/6 and then you get 1,adding 1/8 to 5/8 is only 6/8,so that's how you can tell how it is greater! Hope this helps your daughter!
