How to round up to hundredths?

Rounding a number is a mathematical operation that reduces the number of characters in a number and ultimately gives its approximate value. Guided by special rules, you can round as whole numbers and fractional.

Let us consider specific examples of how to round up to hundredths.

Rounding Rules

In order to round the number to hundredths, it is necessary to leave only two digits after the decimal point after the comma, all the rest should be discarded. At the same time rounding can be done both upwards and downwards. It depends on the number that is in third place after the comma.

  • If in the third place is one of the numbers: 1, 2, 3 or 4 - then we leave the second digit after the comma unchanged.
  • If in the third place is one of the numbers: 5, 6, 7 or 8 - then we increase the second digit after the comma by one.

Examples

Round up to hundredths: 0.1436

In third place after the comma is the number 3, so the second is left unchanged

  • The answer is: 0.14

Round up hundredths: 54,1281

In the third place after the comma is the number 8, which means we increase the second digit by one.

  • Answer: 54,13

There is also a case when the second place is followed by the number 9, and the third - 5, 6, 7, 8, or 9. In this case, when rounding up to hundredths, we have to add 9 to 9, we get 10. We write in second place 0, and we add one to the first digit after the decimal point.

For example, the number 56,798 after rounding will be 56.8.
