Understanding Fraction Comparison
Fractions can be compared just like whole numbers!
We can tell if one fraction is greater than, less than, or equal to another fraction. There are three main ways to compare fractions: using visual models, finding common denominators, or using cross-multiplication.
How to Compare Fractions
1️⃣ Look at the denominators - If they're the same, compare numerators
2️⃣ Find a common denominator - Make the bottoms the same
3️⃣ Use cross-multiplication - Multiply diagonally to compare
Let's Practice Comparing Fractions!
Example 1: Pizza Fractions
Which pizza slice is bigger? \(\frac{3}{8}\) or \(\frac{5}{8}\)?
Since the denominators are the same, we just compare numerators: 3 vs 5.
Example 2: Comparing Different Denominators
Which is greater? \(\frac{2}{3}\) or \(\frac{3}{5}\)?
2/3
3/5
Let's find a common denominator. The least common denominator for 3 and 5 is 15.
\(\frac{2}{3} = \frac{10}{15}\) and \(\frac{3}{5} = \frac{9}{15}\)
Parent Tips 🌟
- Use real-life examples - Compare pizza slices, chocolate bars, or measuring cups to make fractions tangible
- Play fraction war - Use playing cards to make fractions and compare them (great for car rides!)
- Baking math - Double or halve recipes together to practice fraction operations
