Using a calculator you can find that the square root of 65 is 8.062258. To take this to one decimal place you have to first consider only digits up to one decimal place. In this case that would be 8.0 The next step is to look at the second decimal place and assess if we need to round up. If it is 5, 6, 7, 8 or 9 we round up, otherwise we leave the number as it is (round down). In this case, the second decimal is a 6, so we round up. Therefore, the square root of 65 to 1 decimal place is 8.1

To round a number, the decimal place that you want to round to, needs to be specified. If you want to round to the tenths place or to 1 decimal place, then this number is already there: 7.7 is seven and seven tenths. If you want to round it to zero decimal places, or to the nearest whole number, then look at the tenths place and if it is 0-4 you round down to 7, if it is 5-9 (which it is) you round up to 8.
