Think of it this way. In order NOT to change the values of the fractions, you have to be careful to multiply any fractions you are working with by 1. The value 1 can look very different from one; it can be 2/2, 3/3, 4/4, etc. I want to add 1/2 and 2/3. First, I wonder if the smaller denominator 2 is a factor of the larger denominator, 3. It isn't. So, I can multiply the first fraction by 3/3 (which equals 1), and multiply the second fraction by 2/2 (which also equals 1). This will give me the fractions 3/6 and 4/6, which are easy enough to add. If I want to add 1/2 and 3/8, I wonder if the smaller denominator 2 is a factor of the larger denominator, 8. It is. So if I multiply the first fraction by 4/4 (which equals 1) I end up with 4/8 and 3/8, and these are easy enough to add. It might also be possibe to bring the denominators down to the value of smaller factor that is common to each fraction, but values of the numerators may get messy. for example, 3/4 + 8/16 could become 3/4 + 2/4. But if your fractions are 3/4 + 11/16, this will be a little harder to do. I would do 12/16 + 11/16.

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.

Adding fractions with different denominators?
You need to change the denominators so they are the same ( by timesing them together) E.g. 1/7 1/2 7x2=14
Fractions can be added and subtracted only if they're fractions?
We can only add or subtract fractions if they have the same denominators
How do you put the following fractions from least to greatest when the denominators are different?
Multiply or divide both the numeraters and the denominators the same using GCF.Then look at the numeraters. Good luck!!!!!!!

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 are the rules for adding fractions?
Ensure that the denominators are the same when adding or subtracting fractions.
How are adding fractions different?
When adding or subtracting fractions their denominators must be the same
Fractions Have The Same Denominators?
Not always but they need to have the same denominators when adding or subtracting them.
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.
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
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.

How do you subtract improper fractions with different denominators?
It's the same thing as adding or subtracting normal fractions - just make sure both fractions have the same denominators (by either multiplying the denominators or simplifying the fraction - whichever the question needs).
How do you check you math with adding fractions?
When adding or subtracting fractions first make sure that the denominators are the same if they aren't then find the lowest common denominator and alter the fractions accordingly
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.
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.
