What are rational numbers?

Rational numbers are just numbers that can be made by dividing one whole number by another.

Imagine you have a chocolate bar divided into 4 equal pieces, like the ones you get at snack time. If you take 2 of those pieces, you’ve got 2 out of 4, which is the same as 2/4. That fraction is a rational number because it's made by dividing one whole number (2) by another (4).

Think about sharing candy with your friends. If there are 3 kids and you have 6 pieces of candy, each kid gets 6 ÷ 3 = 2 pieces, that’s a rational number too! Even if the numbers aren’t whole, like having 1/2 or 3/4, they’re still rational because you can get them by dividing.

Not all numbers are rational. Some, like π (pi), can't be written as a simple fraction, that’s something we'll learn about later! But for now, just remember: if it can be made from dividing two whole numbers, it’s rational, and it’s part of the fun math world you already know!
