What is a fraction?
You've got one cookie. Your friend wants half. But what IS half? What does it mean to break one thing into pieces and give away part of it? That's where fractions come in — the math tool for sharing, splitting, and slicing up the world.
A fraction is just a number that shows part of something. The bottom number — called the denominator — tells you how many equal pieces the whole thing got cut into. The top number — the numerator — tells you how many of those pieces you're talking about. So 1/2 means "one piece out of two equal pieces."
