Restate question: In working with equivalent fractions, how do you find a missing numerator? (If this is not your question, please resubmit your question with more information.) Example: Find an equivalent fraction for 2/5, with a denominator of 30. Solution: 2/5 = x/30. Since 30 = 5x6, you need to multiply the numerator by 6. 2x6=12. 2/5 = 12/30.
