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.
