To compare two decimals, like 2.1 and 2.088, model each number on a decimal place value chart. To compare which number is greater, start by comparing the digit in the greatest place value (the ones place). Since the ones digits are the same, compare the next greatest digit. In the tenths place, 1 is greater than zero, so 2.1 > 2.088.
