When adding or subtracting fractions with different denominators, changing the denominators so that they have a common denominator is a simple process.
Example: 1/3 + 1/8
What you want to do first is multiply 3 by 8, 3*8=24.
This will be your common denominator.
Next multiply 1/3 by 8/8 so that your answer will have 24 as the denominator.
1/3*8/8=8/24
Now repeat this process with 1/8 by multiplying it by 3/3 to get your 24 denominator.
1/8*3/3=3/24
Now you have both fractions with the same common denominator, all that is left is to add.
8/24+3/24=11/24
And there is your answer.

How do you rewrite a fraction to a percent?
change the fraction in to a decimal by dividing the numerator by the denominator . Then multiply by 100 (same as moving the decimal point left 2 places).
How do you make the denominator the same?
To make the denominator of two fractions the same, you multiply numerator and denominator of one fraction of the fractions by the same number. You may also have to multiply numerator of the other fraction by a different number.For example, to add 1/8 + 1/10, you have to convert to a common denominator; the lowest common denominator is 40, but any common denominator will work (for example, 80 which is simply the product of the two).To convert 1/8 to a fraction with a denominator of 40, multiply numerator and denominator by 5. To convert 1/10, multiply numerator and denominator by 4. The result is:5/40 + 4/40To make the denominator of two fractions the same, you multiply numerator and denominator of one fraction of the fractions by the same number. You may also have to multiply numerator of the other fraction by a different number.For example, to add 1/8 + 1/10, you have to convert to a common denominator; the lowest common denominator is 40, but any common denominator will work (for example, 80 which is simply the product of the two).To convert 1/8 to a fraction with a denominator of 40, multiply numerator and denominator by 5. To convert 1/10, multiply numerator and denominator by 4. The result is:5/40 + 4/40To make the denominator of two fractions the same, you multiply numerator and denominator of one fraction of the fractions by the same number.

To convert 1/10, multiply numerator and denominator by 4. The result is:5/40 + 4/40
What is similar fraction?
Similiar fractions are fractions that have the same denominator.
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.
If two fractions have the same numerator but different denominators is the fraction with the greater denominator greater than or less than the fraction with the lesser denominator?
When the numerators are the same, the fraction with the higher denominator is less than the fraction with the lower denominator. The denominator indicates the size of the "parts" being shown as a fraction, and the higher the denominator, the smaller those parts are!
How do you rewrite a fraction that represents pieces that are the same size?
They are equivalent fractions. Multiply both the numerator (top) and the denominator (bottom) of the fraction by any non-zero integer or divide both by any common factor. You will have an equivalent fraction.
What do you do to the numerator in a lowest common denominator problem?
Multiply the numerator of the fraction by the same amount that you multiply the denominator of that fraction.
How do you rewrite the fraction 60cm over 1m so that the numerator and the denominator have the same units?
1.6ocm {100cm} 3/5
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.
How do you rewrite a fraction to a percent?
change the fraction in to a decimal by dividing the numerator by the denominator . Then multiply by 100 (same as moving the decimal point left 2 places).
How do you subtract mixed fractions when they have the same denominator?
The numerator of the answer is the result of subtracting the numerators of the fractions, and the denominator of the fraction is the same as the common denominator.
What are the steps to adding mixed fractions?
1. 2 3/5+ 3 4/5 Rewrite the mixed numbers as fractions; = 13/5 + 19/5 Write the sum of the numerators over the common denominator; = (13 + 19)/5 = 32/5 Rewrite the fraction as a mixed number; = 6 2/5 2. -2 1/5 + (- 4 5/8) Rewrite the mixed numbers as fractions; = -11/5 + (-37/8) Multiply by 8/8 the first fraction, and by 5/5 the second fraction in order to have the same denominator (because LCD is 40); = -88/40 + (-185/40) Write the sum of the numerators over the common denominator; = -(88 + 185)/40 = -273/40 Rewrite the fraction as a mixed number; = -6 33/40

How do you answer fraction problems?
The best way to answer fraction problems is with a fraction that has the same denominator or a common denominator with those in the original problem. Typically you also need to reduce it so that the final answer does not contain an improper fraction.
How do you change a common fraction to an improper fraction?
Multiply the denominator times the whole number and add the product to the numerator. That number is then the numerator while the denominator remains the same.
What the denominator should be when subtracting a fraction from a whole number?
The denominator should be the same as the denominator of the fraction.
What are the step in subtracting disimilar fraction?
Same as for adding: If the denominators are not equal, you must first find a common denominator, then convert both fractions to that common denominator.
