u basically start by looking at the first number to the right of the decimal...look at only that one number....now which one is biggest...it is the 6 in 0.63....now continue doing that and u will see that the 5 in 0.58 comes next...but then ur left with 2 numbers that have a 0 in that spot...so move over another number (to the right)...and compare those numbers....so the next one is the 6 in 0.06...and lastly, the 0.059.
