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.

To round any number, look at the digit to the right of the place you are rounding to. If the digit is 5 or more, change the digit in the place you are rounding to to the next higher digit. If the digit to the right of the place you are rounding to is less than 5, leave the digit in the place you are rounding to as it is. Change all digits to the right of the place you rounded to to zeros. 56.62 rounded to the nearest tenth is 56.6
