Understanding how to compare and order decimal numbers is a fundamental skill in maths. Let’s take a look at how to arrange the following numbers in order, starting with the smallest:
- 25
- 2
- 18
- 08
- 1
Understanding Decimal Place Value
When comparing decimals, it’s important to understand place value. From left to right after the decimal point, we have tenths, hundredths, thousandths, and so on.
Comparing the Numbers
- Look at the Whole Number Part: All the numbers have a whole number part of 6, so we need to look at the decimal part to compare them.
- Compare the Tenths Digit: Let’s compare the tenths digits:
- 6.25 has a tenths digit of 2
- 6.2 has a tenths digit of 2
- 6.18 has a tenths digit of 1
- 08 has a tenths digit of 0
- 1 has a tenths digit of 1
- Compare the Remaining Numbers: Now, let’s compare the numbers that are left: 6.25, 6.2, 6.18, and 6.1. We already know the tenths digit for these numbers.
- 6.25 and 6.2 both have a tenths digit of 2. We’ll need to look at the hundredths digit to compare them.
- 6.18 and 6.1 both have a tenths digit of 1. We’ll need to look at the hundredths digit to compare them.
- Compare the Hundredths Digit (Where Necessary):
- 6.25 has a hundredths digit of 5. 6.2 can be thought of as 6.20, so it has a hundredths digit of 0. This means 6.2 is smaller than 6.25.
- 6.18 has a hundredths digit of 8. 6.1 can be thought of as 6.10, so it has a hundredths digit of 0. This means 6.1 is smaller than 6.18.
Arranging the Numbers in Order
Now we can arrange the numbers in order, starting with the smallest:
- 08, 6.1, 6.18, 6.2, 6.25
Therefore, the numbers arranged in order from smallest to largest are: 6.08, 6.1, 6.18, 6.2, 6.25
Why is This Important?
Understanding how to compare and order decimals is crucial for:
- Working with measurements
- Understanding financial data
- Solving a variety of maths problems
