Are you ready?
We have used place value to help us order whole numbers before. Let's try a practice problem to help us remember.
Examples
Example 1
Order these numbers from largest to smallest.
73,\ 33,\ 37
671,\ 167,\ 617
We can use a place value table to compare whole numbers.
Order decimals with tenths
This video looks at ways to compare decimals with both units and tenths.
Examples
Example 2
Choose the smaller decimal
We can use a place value table to compare decimals with tenths.
Order decimals with hundredths
In this video we will work through some examples, using a couple of different ways to order the list of numbers. Importantly, remember that it is the place value of the numbers we are comparing.
Examples
Example 3
Which of these sets are arranged from smallest to largest?
We can use a place value table to compare decimals with hundredths.
Rename tenths as hundredths
Sometimes it can be useful when we need to compare a mixture of numbers with tenths and hundredths to renaming the tenths to hundredths. We see an example of this in the next video.
Examples
Example 4
Arrange the following decimals from smallest to largest: 0.7,\ 0.09,\ 0.61
When our numbers have units and tenths, we need to always compare the place value furthest to the left because it has the largest place value. We cannot only look at how long each number is.
