When do you need to find the least common multiple for two or more numbers?
When you are adding or subtracting unlike fractions.
Do you use the Least Common Multiple when subtracting fractions?
Yes.
How is the least common multiple used when adding and subtracting fractions?
When adding and subtracting unlike fractions, find the LCM of the denominators and convert them to it. In this case, it's called the least common denominator, but it's the same process.
What is the least common multiple used for?
It helps with the adding and subtracting of fractions.
When is it useful to find the least common multiple and greatest common factor of two or more numbers to solve a problem?
When you are simplifying fractions or adding and subtracting unlike fractions.
What is least common multiple used for?
When adding or subtracting fractions with different denominators then the least common multiple amongst them is needed to find the lowest common denominator.
Why do people use least common multiple?
To help with adding and subtracting fractions.
How you use the least common multiple?
When adding or subtracting unlike fractions, the LCM process is used to find the least common denominator.
When is it useful to find the LCM or GCF of two or more numbers to solve a problem?
When adding or subtracting fractions with different denominators and when reducing fractions to their lowest termsWhen adding or subtracting fractions with different denominators their lowest common multiple is needed and when reducing fractions to their lowest terms their greatest common factor is needed.
What problems can be solved using Least common multiple?
Adding and subtracting unlike fractions.
What are the Rules of adding and subtracting dissimilar fractions?
If their denominators are different then find their lowest common denominator by means of their lowest common multiple remembering to adjust their numerators accordingly before adding or subtracting.
When adding or subtracting fractions you need to?
Find a common denamonator.
