To get the right answer when you add or subtract unlike fractions.
When adding or subtracting unlike fractions, the LCM process is used to find the least common denominator.
When adding or subtracting fractions with different denominators their lowest common denominator must be found first by using the LCM of their denominators
It helps with the adding and subtracting of fractions.
Least common multiple is needed to find the least common denominator when adding or subtracting fractions with different denominators Greatest common factor is needed when reducing fractions to their lowest terms
Finding the GCF of the numerator and the denominator of a fraction and dividing them both by it will give you the simplest form of that fraction. Finding the LCM of unlike denominators and converting them to it will make it possible to add and subtract unlike fractions.
A Common Denominator
No only when adding or subtracting fractions a common denominator is needed
A common denominator is needed when adding or subtracting fractions of different denominators.
You need a common denominator for both.
a common denominator
No, You only need a common denominator when adding or subtracting fractions.
Adding and subtracting fractions.
A common denominator.
If you are adding or subtracting unlike fractions, convert them to equivalent fractions with a common denominator.
I learned to always change the denominators before adding or subtracting the numerators. You must always have a common denominator before adding or subtracting.
Subtracting fractions is similar to adding fractions. If the fractions have the same denominator, you subtract the numerators. If the fractions have different denominators, you have to convert to a common denominator first.Subtracting fractions is similar to adding fractions.
