The Formula

To compare fractions a/b and c/d, we can use cross-multiplication: If a × d > b × c, then a/b > c/d
If a × d < b × c, then a/b < c/d
If a × d = b × c, then a/b = c/d

Worked Example

Example: Comparing 3/4 and 5/6
Let's compare 3/4 and 5/6. Using cross-multiplication: For 3/4: 3 × 6 = 18 For 5/6: 5 × 4 = 20 Since 18 < 20, it means 3/4 < 5/6. So, 5/6 is the larger fraction.

Tips, Assumptions & Limitations

Always ensure your fractions are in their simplest form before comparing, if possible.
Remember that a larger numerator doesn't always mean a larger fraction if the denominators are different.
Cross-multiplication is a reliable method when finding a common denominator is tricky.

FAQ

The easiest way is to use cross-multiplication. Multiply the numerator of the first fraction by the denominator of the second, and vice-versa. The fraction whose numerator's product is larger is the larger fraction. Alternatively, you can find a common denominator for both fractions and then compare their numerators.

Comparing fractions is a fundamental skill in mathematics. It helps you understand quantities, order numbers, and solve real-world problems involving sharing, recipes, or measurements. It's a building block for more advanced algebra and calculus.
