What is 20.379 to the nearest tenth?

Answer 1

To round a number to the nearest tenth, you first need to consider all numbers at place value tenths and higher. In this case, that's 20.3. Then you look at the next digit along. If it's 5, 6, 7, 8 or 9 you round up, otherwise you leave the number as it is. In this case, the next numbers a 7 so we need to round up. This gives 20.379 to the nearest tenth as 20.4
