When comparing decimals, look at the digits from left to right. Start by comparing the whole-number part. The number with the larger whole number is greater.If the whole-number parts are the same, compare the digits after the decimal point. First the tenths, then the hundredths, and so on—until one number is greater.For example, compare 4.56, 4.5, and 4.63.
The whole-number parts are all 4.
Compare the tenths: 5, 5, and 6. The number with 6 in the tenths place (4.63) is the greatest, so, 4.63 is the greatest decimal.
