Representing 1 as a fraction can be done in many different ways, which is why it can seem hard.
Say you have 1 pie. You cut it into 8 equal slices. So half the pie would be 4 slices (4/8, or 1/2). But what about all 8 of the slices? The fraction of that would be written as 8/8. And that's just the whole pie. It's equal to 1. So 8/8 is the same as 1, you follow?
It works like that. Say you have a cake (following along the dessert theme here.) You cut it into 16 slices. 4 slices is a quarter of the cake, 8 slices is half of it (4/16 can be reduced to 1/4 by dividing, and 8/16 can be reduced to 1/2.) What about all 16 slices of it? Well, that's 16/16. And of course it's the whole cake, which is equal to 1.
You can do this with any fraction, no matter how big it is. 45/45, 90/90, 180/180, they're all equal to 1.
