Decimal fractions are commonly expressed without a denominator, the decimal separator being inserted into the numerator (with leading zeros added if needed), at the position from the right corresponding to the power of ten of the denominator in math.
e.g., 8/10, 83/100, 83/1000, and 8/10000 are expressed as: 0.8, 0.83, 0.083, and 0.0008.
Adding Decimals
When adding two decimal numbers. The decimal numbers should be written in vertical form. Align the decimal point. Example: 0.2 + 0.4 =
Now let us solve this problems.
First arrange in vertical form. The decimal point must be in a straight line


Step 2
2. When adding whole numbers and decimal numbers, change whole numbers to decimal numbers.
Example: 23 + 0.4 =
Arrange the decimal numbers. The decimal point must be in a straight line.


When adding or subtracting decimals, each number must be placed to align the decimal points.
When necessary, zeros are used as place holders to make this possible. Then the operation of addition is performed.
