Order the numbers from greatest to least: 8/25, 0.75, 8/9

First, start off with the one you can tell. 8/25 and 8/9. 8/25 will be before 8/9. because 8/9 is closer to one than 8/25.

you know 8/25 will be the least amount because it's not even halfway to one, but. 75 and 8/9 are over halfway ...75 as a fraction is 3/4 and to make it the same as 8/9 you need to find the least common multiple. the least common multiple is 39, so 3/4*9 = 27/36 and 8/9*4=32/36, which shows us that from greatest to least it should be 8/9, 0.75, then 8/25.
