How do you compare decimal numbers?
In a decimal number, the whole part is to the left of the decimal point. To the right of the decimal point are tenths, hundredths, and thousandths.
First compare the whole part. If that is the same, compare the digits after the decimal point from left to right.
An extra zero at the end does not change the value: 3,5 is the same as 3,50.
- Compare the whole partFirst look at the number before the decimal point.
- Compare after the decimal pointAdd zeros at the end if needed, and compare from left to right.
- Choose the greatest numberChoose the number with the greatest value.
