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 4/7, we can find many equivalent fractions. 4/7 is already in simplest form. The value of 4/7 is 0.571429..., or 57.1429%.

-
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
