The digit 5 is in the tenths place, so its value is 5/10 or 0.5.

Five tenths

5/10

The digit 2 is in the ones place, so its value is 2.

0.253

7 + 0.6 + 0.03 + 0.002

The digit 9 is in the hundredths place, so its value is 9/100 or 0.09.

Six and three hundred ninety-nine thousandths

The largest place value where the digits of two numbers differ. For example, in 3.472 and 3.445, the greatest place-value position where the digits differ is the thousandths place.

A decimal is greater than another decimal when its digit in the greatest place-value position where the digits differ is larger. For example, 3.456 is greater than 3.436 because the digit in the hundredths place (5) is greater than the digit in the hundredths place (3) in the other decimal.

A decimal is less than another decimal when its digit in the greatest place-value position where the digits differ is smaller. For example, 2.453 is less than 2.463 because the digit in the hundredths place (5) is smaller than the digit in the hundredths place (6) in the other decimal.

Arrange decimals from least to greatest by comparing their digits in the largest place-value position. If the digits in the largest place-value position are the same, compare the digits in the next place value, and so on.

Arrange decimals from greatest to least by comparing their digits in the largest place-value position. If the digits in the largest place-value position are the same, compare the digits in the next place value, and so on. The process is similar to ordering from least to greatest, but we start with the largest number.

Given a comparison statement with a missing digit in one of the decimals, replace the missing digit with a value that makes the comparison true.

Two decimals are equal when their digits in all place values are the same. For example, 8.72 is equal to 8.720 because both numbers have the same digits in the ones, tenths, and hundredths place.

Decimals can be written in different ways while representing the same value. For example, 8.72 is the same as 8.720. The zero in the thousandths place doesn't change the value.
