You line the numbers up, one below the other, so that the decimal points are in the same column. You compare the digits in the leftmost column. If one of the digits is large than the other, then that number is bigger. If they are the same, then you move to the next column on the right and repeat the comparisons.
There is, however, one exception to this rule. If any number ends with a recurring 9, that decimal number must be rounded (up) to the last digit before the 9s start. That is 3.564999... recurring should be written as 3.565 for the comparisons. This does not apply to any other digit that might recur.

Why do you need to line up the decimal points before comparing and ordering with decimals?
Because the number in decimal form has a different value based on their position from the decimal point. Every one number left of decimal point it will be valued 10 times. If you don't line them up you can compare them because they might have a different value and you will end up messing your calculation.
What decimal is greater 1.6 or 1.60?
1.60 is greater than 1.6. When comparing decimals, the number of decimal places is important. In this case, 1.60 has two decimal places while 1.6 has only one. The extra zero in 1.60 signifies that it is more precise and therefore greater than 1.6.
What decimal is bigger 0.25 or 0.5?
0.5 is bigger than 0.25. In decimal form, 0.5 is equivalent to 1/2, while 0.25 is equivalent to 1/4. When comparing fractions, the larger the denominator, the smaller the fraction. Therefore, 0.5 is greater than 0.25.
Is 26 greater than less than or equal to 0.3?
26 is greater. 26 is a whole number 0.3 is a decimal number, in decimal numbers the whole numbers go on the left side of the decimal point and the parts of a number (fractions) go on the right side of the decimal point. So . 3 is not even a whole number.
Is 0.480 greater than 0.05?
Yes. Both are less than 1, so compare the decimal parts starting after the decimal point and working towards the right; comparing the tenths: 0.480 has 4 tenths 0.05 has 0 tenths 4 is greater than 0, thus 0.480 is greater than 0.05
