Ordering decimal numbers means arranging them from least to greatest or from greatest to least by comparing their values.
When ordering decimals, always pay attention to the place value of each digit—tenths, hundredths, thousandths, and so on.
To compare decimals, line up the digits by their decimal points and look at each place value from left to right until you find a difference.
Adding zeros after the last digit does not change a number’s value. For example, 0.5 = 0.50 = 0.500.
Each digit in a decimal number has a specific value based on its position. The place value tells how much each digit is worth.
The farther a digit is to the right of the decimal point, the smaller its value becomes.
When decimals look tricky, rewrite them so that each number has the same number of decimal places before comparing.
It helps to think of decimals as fractions with denominators of 10, 100, or 1,000. For example, 0.4 = 4/10 and 0.36 = 36/100.
After ordering decimals, read your list from left to right to see if the numbers increase or decrease correctly.
If a number seems out of order, double-check your comparison by aligning decimal points again.
