Describe in detail the steps for comparing numbers. Use 17.501 and 17.510 as an example
You start by lining up the numbers according to the decimal. Then look at the largest place (tens place) value and compare those 2 digits. 1 and 1 are the same. Move to the next place value down (ones place) and compare those digits. 7 and 7 are the same. Move to the next place value down (tenths place) and compare those digits. 5 and 5 are the same. Move to the next place value down (hundredths place) and compare those digits. 1 is greater than 0, so 17.510 is greater than 17.501
