For Example if the problem is 3/8 + 9/10 = ?
First you would find the least common multiple of each denominator. In this case it would be 80. And you would multiply the denominator and the numerator with the number that equals 80, but you don't have to have the numerator the same answer. So:
3/8 X 10/10 = 30/80
Then you do the other side:
9/10 X 8/8 = 72/80
Now you would just work out the problem:
30/80 + 72/80 = 102/80
Then you would divide the numerator and denominator:
102/80 = 1 11/40

How do you rewrite a fraction so it can have the same common denominator?
To rewrite a fraction so it can have the same common denominator as another fraction, you need to find the least common multiple (LCM) of the denominators of the two fractions. Once you have the LCM, you can then rewrite each fraction with the common denominator by multiplying the numerator and denominator of each fraction by the appropriate factor. This process ensures that both fractions have the same denominator, allowing for easier comparison or addition/subtraction.
How would you use the multiplication rule to find common denominators?
multiply the nominator and denominator of each fraction by the denominator of the other fraction
How do we add rational expressions when the denominators are not the same?
Find a common denominator, which can always be accomplished by multiplying the two denominators together. Then convert each original fraction to the new denominator by multiplying both numerator and denominator by a number that will make the denominator of each fraction the same, then add the converted numerators and express the sum as a new fraction with the sum of the converted numerators divided by the common denominator. For example, a/b + c/d = (da + bc)/bd.
How do you write equivalent fractions with the lowest common denominator?
Well, isn't that just a happy little question! To write equivalent fractions with the lowest common denominator, you first find the least common multiple of the denominators. Then, you rewrite each fraction using that common denominator. It's like painting a beautiful landscape - just take your time, follow the steps, and soon you'll have a lovely set of equivalent fractions.
How do you name two equivalent fractions for each fraction?
Multiply the numerator (top) and the denominator (bottom) of the fraction by any non-zero integer or a common factor. You will have an equivalent fraction.

How would you use the multiplication rule to find common denominators?
multiply the nominator and denominator of each fraction by the denominator of the other fraction
How do you see which fraction is bigger?
The normal way to do it is to get a common denominator and compare the numerators. The simplest way is probably to multiply the numerator of each fraction by the denominator of the other fraction.
How do you change a fraction so they have the same denominator?
First, find a common denominator for the two (or more) fractions. Then, for each fraction, multiply numerator and denominator by the same number (different numbers for different fractions, though), to convert to the common denominator.
What is the least common denominator of a list of fraction?
It is the smallest positive integer which is a multiple of the denominators of each fraction.
What do you get after multiplying each side of the partial fraction decomposition form by the least common denominator what do you get?
You get the original fraction.
How do you subtart fractions?
subtract? Find a common denominator (LCD is preferred). Convert each fraction to an equivalent fraction with the LCD. Add numerators, keep LCD as new denominator. Reduce the fraction.
How do you subtract dissimilar mixed fraction?
To subtract dissimilar mixed fractions, first convert each mixed fraction into an improper fraction. Next, find a common denominator for the improper fractions. Once you have a common denominator, subtract the numerators and keep the denominator the same. Finally, if needed, convert the result back into a mixed fraction.
How to change dissimilar fractions to similar fractions?
Note: numerator is the top part of the fraction, denominator is the bottom part. 1) Find a common denominator. It may be the least common denominator, but it need not be; just multiplying the denominators also gives you a common denominator, not necessarily the smallest one. 2) Convert each fraction so that it has this common denominator. This means multiplying numerator and denominator by the same number.
How do you subtarct dissimilar fractions?
To subtract dissimilar fractions, first find a common denominator for the fractions. This involves determining the least common multiple (LCM) of the denominators. Once you have the common denominator, convert each fraction to an equivalent fraction with that denominator. Finally, subtract the numerators of the adjusted fractions while keeping the common denominator, and simplify the result if possible.
How can you add fractions with different denominator?
To add fractions with different denominators, first find a common denominator, which is typically the least common multiple (LCM) of the two denominators. Next, convert each fraction to an equivalent fraction with this common denominator by multiplying the numerator and denominator by the necessary factors. Once both fractions have the same denominator, add their numerators together while keeping the common denominator, and simplify the result if possible.
How do we add rational expressions when the denominators are not the same?
Find a common denominator, which can always be accomplished by multiplying the two denominators together. Then convert each original fraction to the new denominator by multiplying both numerator and denominator by a number that will make the denominator of each fraction the same, then add the converted numerators and express the sum as a new fraction with the sum of the converted numerators divided by the common denominator.
