To find a missing numerator or denominator in a fraction, you can set up a proportion using the known values. For example, if you have the fraction 2/x = 3/6, you can cross multiply to find the missing numerator: 26 = 3x. Solve for x to find the missing denominator. Alternatively, if you have the fraction y/4 = 5/10, you can cross multiply to find the missing numerator: y10 = 54, and then solve for y to find the missing numerator.

RossOh, 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.
Well, isn't that just a happy little accident! If you're missing a numerator or denominator in a fraction, you can use what you know to solve for it. Look at the known parts of the fraction and use basic math to figure out the missing piece. Just remember, there are no mistakes, only happy little discoveries in the world of numbers!
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 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 the denominator and numerator in a fraction?
Numerator ________ Demomerator
Find the width?
by subtracting the numerator by the denominator
What do you divide first numerator or denominator?
you switch the numerator with the denominator then multiply the numerator first then the denominator.
How do you multipy fractions?
numerator by numerator, denominator by denominator
How can you find the missing numerator or the denominator?
The answer depends on what other information you have.
How can you find the missing numerator and the denominator?
The answer depends on what other information you have.
How do you find the denominator of a fraction if you know the numerator and the value?
Denominator = Numerator/Value

The number in the corresponding place on the fraction that you multiplied is the missing number.
How do you find a missing denominator?
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.
How do you find the denominator and numerator in a fraction?
Numerator ________ Demomerator
Do you divide by the numerator or denominator?
To find a decimal equal to a fraction, you must divide the numerator by the denominator.
How do you do simplest form?
how to find simplest form is: 1. Find the GCF of the numerator and denominator 2. Divide the numerator and denominator by the GCF
How to simplify fractions?
Find the Greatest Common Factor of the numerator and denominator, then divide the numerator by the GCF, and that is the new numerator. Divide the denominator by the GCF, and that is the new denominator.
How do you find a ratio with a denominator of 1?
You divide the numerator by the denominator.
Find the width?
by subtracting the numerator by the denominator
Has a numerator and denominator?
A fraction has a numerator and a denominator.
