Compare and Order Decimal Numbers

Decimals can seem tricky! I like to think of decimals as money....
Let's compare these two numbers: 125.55 and 125.75


Would you rather have $125.55 or $125.75...the second choice is more money.


Another way to compare decimals is to stack up the numbers and then compare. Let's order these decimals from greatest to least.
0.558
0.422
0.431
*First look at the largest place value on the left...each of our numbers begin with a 0 so we'll move to the next value.

*Now look at the tenths. We have 5, 4, and 4. We know that 5 is bigger than 4. That tells us that 0.558 is the largest number. Our other digits are both 4 so we need to look at the next place value.

*Now look at the hundredths. Since we already found where 0.558 belongs we don't have to compare it any more. Our values are 2 and 3. Since 3 is larger than 2 we have our order!

* 0.558, 0.431, 0.422
