The denominator tells you, in effect, what kind of fraction you have, whether it is halves, thirds, quarters, fifths, sixths, and so forth. You can add a group of thirds to another group of thirds and then find out how many thirds you have in total, but if you try to add thirds to quarters, what do you get? Not thirds, and not quarters, but some mix of the two. What is the sum of 2 apples and 3 Oranges? Five fruit. This doesn't work for numbers, however. The sum of 1/3 and 1/4 is two fractions, but that doesn't tell you anything, you want a specific number. You can get that by converting them both to twelfths. Then you have 4/12 and 3/12 which adds up to 7/12, an actual number.

Fractions Have The Same Denominators?
Not always but they need to have the same denominators when adding or subtracting them.
What way is subracting fractions with unlike denominators like adding fractions with unlike denominators?
If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators.
Can you multiply fractions that have a different demonminator?
Yes. When multiplying and dividing fractions your denominators do not have to be the same. The denominators only haveto be the same if you are subtracting or adding them.
When adding fractions do denominators change?
you must make the denominators the same first in order to add them once they are added, the denominators stay the same and the top combines
When adding or subtracting fractions do you have to have the numerator the same or denominator?
The denominators must be the same, the numerators can be different.

How is adding like fractions and adding unlike fractions the same?
If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators. To add fractions with unlike denominators, rename the fractions with a common denominator. Then add and simplify.
How are adding fractions different?
When adding or subtracting fractions their denominators must be the same
What are the rules for adding fractions?
Ensure that the denominators are the same when adding or subtracting fractions.
What way is subracting fractions with unlike denominators like adding fractions with unlike denominators?
If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators.
Are the steps for like and unlike denominators the same or different?
It depends what you are doing with the fractions. If you are multiplying or dividing fraction, the denominators do not need to be the same and the calculation can be carried out immediately. If you are adding or subtracting fractions, the denominators must be the same; if you have different denominators, the fractions must first be changed into equivalent fractions with the same denominator. When the denominators are the same (or have been made the same as equivalent fractions from being different) the calculation can be carried out.
How do you minnous fractions?
Subtracting fractions is similar to adding fractions. If the fractions have the same denominator, you subtract the numerators. If the fractions have different denominators, you have to convert to a common denominator first.Subtracting fractions is similar to adding fractions.

When adding fractions with unlike denominators it is most helpful if the fractions are renamed using the?
If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators. To add fractions with unlike denominators, rename the fractions with a common denominator.
Adding unlike fractions?

To do this, you need to find the least common multiple (LCM) of the two denominators. To add fractions with unlike denominators, rename the fractions with a common denominator. Then add and simplify.
Do you find the GCF or LCM when adding fractions?
When adding fractions, you want to make sure that the denominators are the same. It's the same process as the LCM.
What is the secret to adding fractions?
When adding or subtacting fractions make sure that the denominators are of the same values if they are not then find the lowest common denominator.
