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.

Missing....? But the answer to find the missing is normally either "algebra" or "find another equation to use."
You can find a missing denominator if you know something that the fraction is equal to. Then you can find the missing denominator through cross multiplication.
The answer depends on where it is missing from.
It depends on what measure is missing.
Take the denominator (bottom # of fraction) and multiply it by the whole number. Then, add that # to the neumorator (top # of fraction) . Put the total number over the original denominator.
