The trick to comparing decimals is to STACK THEM ON TOP OF EACH OTHER. LINE UP THE DECIMALS to keep all of the digits in order based on their value. Then you compare each digit, one place at a time (like you would for ABC order!).
Now, if you are a sloppy writer, unlike me who has beautiful writing (quit laughing) you can take your lined notebook paper and turn it on its side. Use the blue lines to keep your place values all lined up.
