Question

5.449=5.45 how to round up this? ​

Answer 1

Answer:

If the last digit is greater than or equals to 5

then we increase the previous digit by one

and

If the last digit is less than 5 ,then we did not change the previous digit ( remains the same).

Example

5.449

last digit is 9 which is greater than 5 , then we will increase the previous digit (i.e. 4) to 5

so the answer is 5.45
