When rounding 1.8 to the nearest whole number, we look at the digit in the tenths place, which is 8. Since 8 is greater than or equal to 5, we round the number up to the next whole number. Therefore, 1.8 rounds to 2.

The key to rounding any number to the nearest ten does not use the decimals at all. In fact, you only need to check the digit in the ones place. If the number in the ones digit is below 4, then round down. If the number in the ones digit is 5 or larger, round up. Some Examples: 563 ---> 560 - The ones digit is a three, you round down 27 ---> 30 - The ones digit is above five, you round up 145 ---> 150 - The ones digit is a five, you round up 890 ---> 890 - The ones digit is a zero, you do nothing because it is already a ten.
