When you compare two decimal numbers, follow this order:
- Compare the whole number parts to the left of the decimal points.
- If the whole number parts are the same, compare the tenths digits.
- If the tenths digits are the same, compare the hundredths digits.
Example 1
Which is bigger, 35.67 or 35.71?
Answer
Look at:
35.67
35.71
The whole number parts are both 35, so compare the tenths digits.
35.67
35.71
7 is bigger than 6
So 35.71 is bigger than 35.67.
Example 2
Which is bigger, 13.37 or 13.31?
Answer
Look at:
13.37
13.31
The whole number parts are both 13, so compare the tenths digits.
13.37
13.31
The tenths digits are both 3, so compare the hundredths digits.
13.37
13.31
7 is bigger than 1
So 13.37 is bigger than 13.31.
Example 3
Which is bigger, 24.07 or 12.71?
Answer
Look at:
24.07
12.71
The whole number parts are 24 and 12.
24 is bigger than 12
So 24.07 is bigger than 12.71.
