Adding Decimals and Zeros

Decimal number is a number. It must divide in to two parts. It’s called whole number part and a fractional part. The dot (.) is indication of the decimal point. For example: 721.453.

Here the 7 represent 700.
2 represent 20.
1 represents 1 unit.
1 represent tenth place.
5 represent hundredths Place.
Second 3 represent thousandths place.


Addition with a decimal point:

Adding of decimals:

Steps:

First we need to write the given question in a correct way.

Here we need to add the columns from right to left.
