What Is a Fraction?
A fraction represents a part of a whole. When something is split into equal pieces, a fraction tells us how many of those pieces we are talking about.
Every fraction has two parts:
- Numerator โ the top number. It tells how many parts we have.
- Denominator โ the bottom number. It tells how many equal parts make up the whole.
Example: means the whole was cut into 4 equal parts, and we have 3 of them.
Imagine a chocolate bar broken into 4 equal squares. If you eat 3 of the squares, you ate of the bar.
๐ Key Idea: The parts must be equal in size. Three random-sized chunks out of four is not .
