Round decimals

Let's learn the concept of round decimals in today's learning.

Rounding decimals involve few steps and these are listed below:

Step 1) Identify the decimal point.
Step 2) If the immediate number after decimal point is 5 or more than 5, round it by adding 1 to it.
Step 3) If the immediate number after decimal point is less than 5 than, round it to the same number removing the value after decimal point.

Decimals can be rounded to the nearest tens, hundredths, thousandths and so on. To understand this better, one has to be clear about the decimals and place value concept.
