What is half of 9

half

A half is created when you divide a whole into two equal parts and take one of these parts. You can therefore also write half as a fraction: In the denominator (lower number) there is a 2, since it was divided into two parts. There is a 1 in the counter (upper number) because you took a part. It will look like that: . As a decimal you write half 0.5. That's why you calculate the fraction, i.e. divide 1 by 2: 1: 2 = 0.5.

This is how one half is created:That's how it looks:
You have a whole chocolate cake here. It consists of 1 piece.

This chocolate cake is now cut in half. This creates 2 pieces of the same size. Each piece represents half of the chocolate cake (written as a fraction: ).

Now you take 1 of these half pieces. What you have is half of the whole chocolate cake (written as a fraction: ).

If you divide a whole into two equal parts and take one of those parts, you have half.
