What is Rounding up Decimals?

Rounding decimal number is a very important skill of maths and practical life. If you are asked how much marks you got in the exam, instead of saying you got 94.5 you can simply say about “95”. We round up decimal numbers to find the approximate value of a specific number in a specific context.

How to Round up numbers ?  To round off any number we have to look at the next digit on the left hand side of our number. If the next digit is any less than 5 we will round it down and it is more than 5 we will round it up. Rounding decimals if possible to the near whole numbers, tenths or hundredths.

Rounding to the nearest Tenths

To round off a decimal number to the nearest tenth, following steps can be followed:

  • Identify (you can circle) the number that you want to round off.
  • Carefully mark the digit in the place of the “tenths”
  • See the ‘hundredths’ place, If our digit in the “hundredths” place is 0 or 1 or 2 or 3 or even 4, we will round down the number at the place of the tenths to the nearest “tenths”. However, If our digit is in the hundredths place of 5, 6, 7, 8 or 9 then you will round up the number at the place of the tenths to the nearest tenths. Finally remove all the digits to the right of the tenth column. The number which is visibly left out is your answer.

For example, 9.76 rounded off to its nearest tenth is 9.8

Rounding to the Nearest Hundredths

To round off a decimal number to the nearest hundredth, following steps can be followed:

  • Identify (you can circle) the number that you want to round off.
  • Carefully mark the digit in the hundredths place.
  • See the ‘thousandths’ place, If the given digit in the thousandths place is 0, 1, 2, 3 or 4, we will round down the place of the hundredths to the near hundredth but If the digit in the thousandths column is 5, 6, 7, 8 or 9, we will round up the hundredth place to the near hundredths. Similar to earlier solution, our answer is the left out one after removing all of the right hand side digits. For example, rounding off 5,872.158 to its nearest hundredth would be 5872.16.
