Advanced Topics
Fractions and Their Uses
Understanding Fractions
Fractions show parts of a whole. When you split a pizza into 4 equal slices, each slice is \( \frac{1}{4} \) of the pizza.
Parts of a Fraction
- The top number is called the numerator (it tells how many parts you have).
- The bottom number is called the denominator (it tells how many parts the whole is split into).
Comparing and Using Fractions
You will learn to compare fractions like \( \frac{1}{2} \) and \( \frac{1}{4} \), and to find fractions on a number line.
Fractions Around Us
Fractions are everywhere—slicing apples, measuring ingredients, or sharing candy.
Key Formula
\[\frac{a}{b}\]
Examples
Shade \( \frac{2}{3} \) of a rectangle.
Which is bigger: \( \frac{3}{4} \) or \( \frac{2}{4} \)?
In a Nutshell
Fractions are equal parts of a whole, like slices of a pizza.
