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 11th decimal 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.
To the nearest tenth, 49.9 To the nearest ten, 50
To the nearest ten, 10 To the nearest tenth, it's already there.
The nearest 10th is 0.1.

68,548 rounded to the nearest 10th
To round to nearest 10th, look at the 100th place. If it is 5 or more, round the 10ths place up, otherwise leave it the same, and drop the rest of the decimal. So 5.524 rounded to the nearest 10th is 5.5, since the 100ths place is 2.
To the nearest 10th means rounding to one place after the decimal. So to round a whole number to the nearest 10th you would just put the number '.0' I guess. e.g 1 would be 1.0

The nearest 10th is 0.1.
2 < 5, so we know that we have to round down for the 10th place:4.7.
