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.
If you have 2 fractions like this: 2/4 and ?/8 First, 8 Divided by 4 is 2, so multiply 2x2, equals 4. The answer is 4/8

How do you find missing numerator or denominator?
Oh, dude, it's like super easy. So, if you're missing a numerator, just multiply the denominator by the whole number and add the missing part. And if you're missing a denominator, divide the numerator by the whole number and subtract the missing part. It's like math, but with a side of detective work.
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 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.
