Working with Fractions

Pieces of the Whole

Fractions show parts of a whole. Imagine sharing a pizza—each slice is a fraction!

What’s a Fraction?

A fraction has two parts:

  • Numerator (top): How many parts you have.
  • Denominator (bottom): How many equal parts altogether.

So, \( \frac{3}{4} \) means 3 out of 4 equal parts.

Comparing and Using Fractions

  • To compare fractions, make the denominators the same.
  • To add or subtract, the parts must be equal-sized.

Why Fractions Matter

Fractions are used in recipes, sharing, measuring, and even telling time!

Key Formula

\[\frac{a}{b}\]

Examples

  • Eating 2 out of 8 slices of pizza is \( \frac{2}{8} \) or \( \frac{1}{4} \) of the pizza.

  • Measuring half a cup of milk for pancakes.
