The key to
comparing:
DECIMALS!

fractions and percents to DECIMALS.
• After you have converted them to
DECIMALS, you will have no problem
ordering them :)

• Convert all fractions into decimals using NIDO!
• Line up the decimals!
• Even the playing field by plugging in place holding zeros.
• Compare the numbers from left to right!
• Put back in original form...
If you can do all of that...
0.3, 0.35, 2/5, 0.45, 0.5
•Then you can
order
decimals!
