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 what should you do first?
For adding or substracting fractions first of all we should calculate the LCM( Lowest Common Multiplier) of the denominators in both of the fractions.
What is the definition of adding and subtracting fractions with unlike denominators?
What is the definition of Adding and Subtracting Like Fractions
Fractions Have The Same Denominators?
Not always but they need to have the same denominators when adding or subtracting them.
What is the most important thing you can say about adding or subtracting fractions?
the most important thing is to change the denominators so u can make common denominators
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.
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.
When adding or subtracting fractions what should you do first?
For adding or substracting fractions first of all we should calculate the LCM( Lowest Common Multiplier) of the denominators in both of the fractions.
What you must have when you adding fractions?
Common denominators.
What is the definition of adding and subtracting fractions with unlike denominators?
What is the definition of Adding and Subtracting Like Fractions
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.

Fractions Have The Same Denominators?
Not always but they need to have the same denominators when adding or subtracting them.
When adding fractions with like denominators how do you convert?
When adding fractions with like denominators, add the numerators together and put the result over the denominator. Simplify if possible.
What is the most important thing you can say about adding or subtracting fractions?
the most important thing is to change the denominators so u can make common denominators
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
Do you have to change the denominators when multiplying fractions?
No. To multiple fractions multiple the numerators together and multiply the denominators together and simplify (by dividing both numerator and denominator of the result by common factors until the only common factor is 1). The denominators only need to be the same when adding or subtracting fractions.
