Well, isn't that a happy little number! When we round 618.4 to the nearest hundredth, we look at the digit in the thousandths place, which is 4. Since 4 is less than 5, we keep the hundredths place as it is, making 618.4 rounded to the nearest hundredth still 618.4. Just a little touch-up to keep things nice and precise!
618.4 rounded to the nearest hundredth is 618.40. When rounding to the nearest hundredth, we look at the digit in the thousandth place, which is 4 in this case. Since 4 is less than 5, we do not round up the digit in the hundredth place, which remains as 0. Therefore, 618.4 rounded to the nearest hundredth is 618.40.
