Just plugging this into a calculator and replacing the x values with 15 and 25 respectively, both of them exceed 5,000. Meets is the answer for both of them.
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!
