The order would be 90.009, 90.56, 90.6, and 90.698.
All you have to do is look and compare the numbers. For example, 90.009 versus 90.56. If you look 90.009 has to zeros first but 90.56 has a five in the tenths place. Because there’s a five in the tenths place in 90.56 but a zero in 90.009, 90.56 would be larger. Hope this helps :)
