When doing changing fractions to equivalent fractions, if you multiply or divide the denominator by a number, you have to do the same to the numerator. Here is an example:
2/3 + 4/5 =
To find the LCM of 3 and 5, list the multiples of each until you find one that they have in common:
3, 6, 9, 12, 15, 18...
5, 10, 15, 20...
15 is the LCM.
To change the 3 in 2/3 to 15, multiply it by 5. Since you multiplied 3 by 5, you have to multiply the 2 by 5. The equialent fraction is 10/15.
To change the 5 in 4/5 to 15, multiply it by 3. 3 x 5 = 15. Now, you have to do the same to the numerator 4. 3 x 4 = 12. The fraction is 12/15.
Now, you can add the fractions together:
10/15 + 12/15 = 22/15, but it is an improper fraction, so you need to change it to a mixed number. To find the whole number, divide the numberator by the denominator. 22 divided by 15 is 1 with a remainder of 7. Use the 7 as the numerator and the 12 (the number you divided by) as the denominator.
The answer is 1 7/12. It is in simplest form because 7 is a Prime number that will not divide evenly into 12.

What is the missing numerator 412 3?
To find the missing numerator in the expression "412 3," it seems you might be referring to a fraction or mixed number. If you meant to express a mixed number like ( \frac{412}{3} ), the numerator is 412. However, if you are looking for a specific mathematical operation or context, please provide more details for a precise answer.
How do you do to find a missing number on an equivalent fraction?
An equivalent fraction is just a multiple of the one that you have (i.e it is the one that you have, scaled up or down). So multiply the fraction that you have until either the numerator or the denominator match the given numerator/denominator of the fraction with the missing number. The number in the corresponding place on the fraction that you multiplied is the missing number.
How do you find missing numerator or denominator?
If you have 2 fractions then you do cross multiplication where you take the left numerator and times it by the right denominator if your looking for the numerator. If your looking for the denominator then you do the same thing only you use the top as your divider not the bottom. Well if it is an equation with another fraction equaling it, you can multiply the denominator by a number that will allow it to have the same value of the denominator in the other fraction. Once you know that number ( the one it took so the denominators were equal when multiplied) you just divide the fraction ( the one you have both denominator and numerator) by that number, and put it over the original lone denominator, then you have your answer. If you only have the numerator you use pretty much the same concept except opposite the steps. Here's an example: 7/? = 21/30 You would know 7 multiplies with 3 to get 21, so you divide 30 by 3 (the number it took to get 7 to be 21), and you get 10. Then you put the 10 underneath the original 7/? resulting in the answer being 7/10. So 7/10=21/30. Hope this is the answer you were looking for.
How do you find missing neumorator?
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.
