Adding unlike fractions?
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.
When adding or subtracting two fractions with denominators that are not equal what is the first step you take?
When adding or subtracting fractions with different denominators, the first step is to find a common denominator. This involves finding the least common multiple (LCM) of the two denominators. Once you have a common denominator, you can then add or subtract the numerators of the fractions accordingly.
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.
Do you need a common denominator when adding fractions?
Yes, you must convert both fractions to the same denominator to add them. Now... Do the rest of your homework yourself!
How do subtract fractions?
all you have to do is follow the same algorithm for adding a pair of fractions together. the main step is to find common denominators between the two. to do this, you need to find the least common multiple. another way you could find a common denominator is just by changing them into decimals, and adding them normally like whole numbers with the decimals lined up correctly.
Do you need a common denominator for dividing fractions?
No only when adding or subtracting fractions a common denominator is needed
Does division need a common denominator?
No, You only need a common denominator when adding or subtracting fractions.
Do you need common denominator when adding fractions?
Yes.
How is subtracting fractions like adding fractions?
You need a common denominator for both.
Adding unlike fractions?

Why do fractions need a common denominator before you add or subtract?
Because the answers will be wrong when adding or subtracting them if they don't have a common denominator.
Why do fractions need to have a common denominator before subtracting or adding?
Because if there's no common denominator it'll be hard to simplify. And will cause you to get a headache.

How do you get the common denominator for dividing fractions?
You don't need a common denominator to divide fractions.
Do you need a common denominator for all fractions before doing the order of operations?
You DO need a common denominator to add, subtract, or compare fractions. You DO NOT need a common denominator to multiply or divide fractions.
