How can knowing the LCM help you add subtract and multiply fractions?
When adding and subtracting unlike fractions, it is necessary to find the LCM of the denominators, called the least common denominator. Once you have found the LCD, you can convert the fractions to equivalent fractions with a common denominator and proceed with the adding and/or subtracting. Finding an LCM will have no effect on multiplying fractions.
What is the least common multiple of the denominator of two or more fractions is their?
least common denominator
How can knowing the greatest common factor and lowest common factor help when you add subtract and multiply fractions?
The least common factor of any set of numbers is 1, so that doesn't help at all. Finding the GCF of the numerator and denominator and dividing them by it will help to simplify a fraction. Finding the least common multiple of the denominators (called the least common denominator) will help when you add and subtract fractions. None of those are needed to multiply fractions.
What common denominator of two fractions is the least common multiple of the two denominators?
The least common denominator of two fractions is the least common multiple of the two denominators.
What is it called when The denominator is a common multiple of the denominators of two or more fractions?
the least common denominator
Do you multiply the common denominator in fractions?
you do not do that
How do you get a common denominator for subtracting fractions?
Just multiply the two denominators of your fractions, the answer you get is a common denominator.
How do you add improper fractions if the denominator can't multiply into the other denominator?
You Ned to find a larger common denominator or multiply the denominators to gain a common denominator.
Do you need a common denominator to multiply fractions?
No.
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.
How to do inequality fractions?
It helps to find a common denominator and multiply both sides of the inequality by this common denominator. That way, you have an inequality without fractions.
Do you need to find a common denominator when you multiply fractions why or why not?
one-sixth
When multiplying fractions when they have same common denominator do you multiply the denominators?
YES.
When you multiply fractions do you multiply the denominator?
yes. you multiply the numerator and denominator
How do you multiply fractions with same denominator?
multiply denominator by denominator and vice versa
How can you find common denominator for two unlike fractions?
multiply the two denominators
Do you multiply the denominator when you multiply fractions?
Yes you do.
