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.
