How do you add and subtract unlike denominators?
you make them have like denominators by multiplying so many times that they have the same denominators or you can make them have like denominators by multiplying the two
What are denominators of the same size called?
They are the same denominators.
What are denominators and numerators called?
They are called denominators and numerators!
How do you write fractions with common denominators?
multiply the denominators
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 frcations with uncommon deniminator?
No. you must make the denominators the same
How do you multiply fractions with uncommon denominators?
To multiply fractions all you do is multiply the numerators and the denominators separately eg: 4/7 x 6/11 = 24/77. The "commonality" of denominators has no relevance.
How do get the answer for dividing uncommon denominators?
When A/B is divided by C/D, just flip C/D into D/C and multiply. Outcome should be AD/BC.
Why do you need a common denominator when you add fractions?
Unless you are using a calculator that adds them for you, it is much harder to add fractions with uncommon denominators. Having the same denominator allows you to only have to add the numerators for your answer.
What is unrelated denominators?
Denominators which have no common factors
How do you add and subtract unlike denominators?
you make them have like denominators by multiplying so many times that they have the same denominators or you can make them have like denominators by multiplying the two
How do you write fractions with common denominators?
multiply the denominators
What are denominators and numerators called?
They are called denominators and numerators!
What are denominators of the same size called?
They are the same denominators.
What is the lowest common multiple of the denominators?
You have to state the denominators to expect an answer
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 are common multiples and common denominators the same and different?
Common multiples and common denominators can be found using the same process. They differ in their function. Common denominators are common multiples that are functioning as denominators.
