Fractions Examples in Math
Start with the recap, study the fully worked examples, then use the practice problems to check your understanding of Fractions.
This page combines explanation, solved examples, and follow-up practice so you can move from recognition to confident problem-solving in Math.
Concept Recap
A number representing a part of a whole, written as one integer over another non-zero integer.
A pizza cut into 4 slices—eating 1 slice means you ate \frac{1}{4} of the pizza.
Read the full concept explanation →How to Use These Examples
- Read the first worked example with the solution open so the structure is clear.
- Try the practice problems before revealing each solution.
- Use the related concepts and background knowledge badges if you feel stuck.
What to Focus On
Core idea: Fractions represent division and parts of wholes simultaneously.
Common stuck point: Larger denominator means smaller pieces, not larger fraction.
Sense of Study hint: Draw two same-sized rectangles, split one into the denominator's number of parts, and shade the numerator's count to see the actual size.
Worked Examples
Example 1
easySolution
- 1 Check that the denominators are the same: both fractions have denominator 5.
- 2 Since denominators match, add the numerators directly: \frac{2 + 1}{5} = \frac{3}{5}.
- 3 Simplify: \gcd(3, 5) = 1, so \frac{3}{5} is already in lowest terms.
