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 fourth 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 get the decimal, divide the numerator of the fraction by the denominator. If the decimal runs to more than one place, then you have to round it to one decimal place.
Go to the second decimal place; if it is less than 5; round down. If it is 5 or greater, round up. So, 1.51 rounded to 1 decimal place is 1.5.

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 one decimal place it is 4.1
