Decimal numbers are just like whole numbers, but with an added decimal point to show parts of a whole.
When you work with decimal numbers, you can perform the same operations as with whole numbers, such as addition, subtraction, multiplication, and division.
For example, let's say you have the decimal numbers 2.5 and 1.6 and you want to add them together. You would add the numbers just like you would with whole numbers, and then place the decimal point in the answer based on the number of decimal places in the original numbers.
Here's how to do it:
2.5
1.6 4.1
The decimal point is in the same place as in the original numbers.
The same process can be used for subtraction, multiplication, and division. Just be careful to pay attention to the decimal point and place it correctly in the answer. With a little practice, you'll be working with decimal numbers like a pro!
