Study Notes
- Ordering decimals involves lining up decimal points to compare place values, similar to adding and subtracting numbers.
- Decimals with different numbers of digits should have zeroes added to make the number of digits equal, without changing the value.
- To compare decimal numbers, write them with lined up decimal points and compare place values from left to right.
- If the place values are the same in both numbers, move to the next place value to compare.
- The number with the larger digit in the current place value is the larger number.
- In the example provided, 8.019 is larger than 8.03 because the hundredths place value is larger in the first number.
- In another example, 4.006, 4.13, 4.31, and 4.06 are put in order as 4.31, 4.13, 4.06, and 4.006 by lining up decimal points and comparing place values.
