Decimal Operation

Adding with Decimals

When you add with the decimals you add them as usual but you need to allign the decimal point.

For example:

2.60 + 7.28= 9.88

Subtracting with Decimals

when you subtract a decimal you need to allign the decimal with the other decimal so when you add you can get right the place of the decimal point.

For example:


3.60

-2.40

---------

1.20

Multiplying Decimals

When you multiply an operation with decimales you just add the spaces of the decimal point so you need to count the # of spaces in the answer so you add the decimal point.

For example:

3.670*4.8=17.616

Dividing decimals

When you divide a whole number with a decimal is the easy operation. First you need to take the decimal point up of its place. Then you can divide.

For example:

3÷1.5= 0.5
