How do you round to the nearest tenths?

Answer 1

If you have a number with more than one digit after the decimal point, if the second digit is 5 or greater, you round up, but if the digit is 4 or less, you round down. For example:

Rounding 6.84 to the nearest tenth: 6.8

Rounding 6.847 to the nearest tenth: 6.8

Rounding 6.86 to the nearest tenth: 6.9

Rounding 6.85 to the nearest tenth: 6.9

Sometimes it is advantageous to express a value in round numbers. To round to a particular place, look at the digit immediately to the right of the one you want to round to, in this case, the hundredths place. If that digit is 4, 3, 2, 1 or 0, zero it and everything to the right of it out. If that digit is 5, 6, 7, 8 or 9, increase your target digit by one and zero everything to the right of it out. If your target digit is 9, it will become a zero and increase the digit to the left of it by one.

Answer 3

When a number is 0, 1, 2, 3 or 4 it rounds down. When a number is 5, 6, 7, 8 or 9 it rounds up. So for example, the number is 1.23 the hundredths digit is a 3 so you round down to 1.2.
