How do you add and subtract mixed numbers with unlike denominators?
just change the fration with the smallest denominator and add or subtract the way you always do.
How do you add or subtract fractions with unlike denominators?
convert at least one of them so that they have the same denominator, then proceed with the addition or subtraction
How do you subtract fractions without alike denominators?
Convert unlike fractions to equivalent fractions with common denominators by finding the LCM of the denominators.
How do you add and subtract by fractions?
If the fractions have the same denominator, add and subtract the numerators as if the denominators weren't there and put the result over that denominator. Reduce if possible. If the fractions have different denominators, find the LCM of the denominators and convert the fractions to equivalent fractions with like denominators. Then add and subtract the numerators as if the denominators weren't there and put the result over that denominator. Reduce if possible.
How do you add and subtract fractions with unlike denominators without finding a common denominator?
The fastest and surest way to do that is to have a calculator that has a fraction button. (a b/c)
When you add or subtract fractions with unlike denominators why do you have to find LCM?
Because to add fractions, the denominators must be equal.
How do you add and subtract mixed numbers with unlike denominators?
just change the fration with the smallest denominator and add or subtract the way you always do.
Why do fractions need to have unlike denominator before you add or subtract them?
The question is based on a complete misunderstanding of what is required. Unlike denominators are NOT required!
How do you add or subtract fractions with unlike denominators?
convert at least one of them so that they have the same denominator, then proceed with the addition or subtraction
What is the benefit of getting the least common multiple of two or more numbers?
It will enable you to add and subtract fractions with unlike denominators.
How would you add or subtract fractions with like denominators?
The same way you would add or subtract whole numbers, leaving the denominators alone.
How do you subtract Fractions with models unlike denominators?
The denominators need to be the same for subtraction. Find the Least Common Denominator for both items and then subtract.
How do you subtract fractions without alike denominators?
Convert unlike fractions to equivalent fractions with common denominators by finding the LCM of the denominators.

How do you add two fractions that have like denominators?
In fractions, you can NEVER add or subtract
What do you not have to think about when you add or subtract fractions?
Whether the denominators are common or not.
