Worked Example
Show that 3/4 is equivalent to 9/12:
1
Identify scale factor
12 / 4 = 3
Find factor that scales denominator 4 to 12.
2
Multiply numerator and denominator by 3/3
(3 * 3) / (4 * 3) = 9 / 12
Multiplying by 3/3 is equivalent to multiplying by 1.
✓Verification Check
Verify by cross-multiplication: 3 * 12 vs 4 * 9.
3 * 12 = 36
•
4 * 9 = 36
⚠️ Common Pitfalls & Misconceptions
Adding instead of multiplying to find equivalent fractions
✗ Thinking 3/4 = (3+2)/(4+2) = 5/6✓ Multiply or divide numerator and denominator by the same non-zero number
Addition changes the relative proportion.
