🍕 What is a Fraction?
A fraction represents a part of a whole. When we cut a pizza into 4 equal pieces and eat 1 piece, we've eaten ¼ (one quarter) of the pizza. Fractions are everywhere — in cooking, music, time, and everyday life!

Same Value, Different Look
Some fractions look different but have the same value:
½ = 2/4
½ = 3/6
¼ = 2/8
Rule: Multiply or divide both top and bottom by the same number!
➕ Working with Fractions
Adding Fractions (same denominator)
Just add the numerators:
1/4 + 2/4 = 3/4
Adding Fractions (different denominator)
Find a common denominator first:
1/2 + 1/4 = 2/4 + 1/4 = 3/4
Multiplying Fractions
Multiply tops together, bottoms together:
1/2 × 1/3 = 1/6
