Understanding Equivalent Fractions
Equivalent fractions are fractions that represent the same value despite having different numerators and denominators. They are created by multiplying or dividing both the numerator and denominator by the same non-zero number.
For the fraction 3/4, we can find many equivalent fractions. 3/4 is already in simplest form. The value of 3/4 is 0.75, or 75%.

How to Find Equivalent Fractions
- Start with the fraction - Begin with 3/4
- Choose a multiplier - Pick any number (2, 3, 4, 5, etc.)
- Multiply both parts - Multiply numerator AND denominator by the same number
- Verify - Check that 6/8 = 3/4 by cross-multiplying

Simplifying Fractions
A fraction is in simplest form when the numerator and denominator have no common factors other than 1. 3/4 is already in simplest form.
To simplify, divide both numerator and denominator by their greatest common divisor (GCD). The GCD of 3 and 4 is 1.
Common Mistakes to Avoid
Warning: Watch Out For These Errors
-
Mistake: Multiplying only the numerator or only the denominator
Correct: Always multiply BOTH by the same number -
Mistake: Adding the same number to numerator and denominator
Correct: MULTIPLY both parts, don't add -
Mistake: Assuming equivalent fractions look the same
Correct: They have different numbers but the SAME value
