First you find a common multiple of the denominators. The least common denominator is handy but not essential. This number will be the denominator of the answer - before simplification.

For both fractions find an equivalent fraction whose denominator is this common denominator.

Carry out the subtraction on the new numerators to give the numerator of the answer.

Simplify the result for the final, simplified answer.

A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

Anything having to do with adding or subtracting unlike fractions.


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.


How you use the least common multiple?

When adding or subtracting unlike fractions, the LCM process is used to find the least common denominator.


How are equivalent fractions used in renaming when subtracting?

When subtracting one fraction to another, one or both fractions are renamed so that they have the same denominators. Then the result of the subtraction is the equal to the subtraction of the numerators divided by the common denominator.


Is Least Common Denominator used for subtracting fractions?

Yes.


What is the least common multiple used for?

It helps with the adding and subtracting of fractions.


Why is it important to learn about equivalent fractions?

Answer: When adding or subtracting fractions with different denominators it is important to change the denominators into the lowest common denominator by using equivalent fractions. Answer: Equivalent fractions are used to: * Simplify fractions. It is sort of inelegant to write the final solution of a problem as 123/246, when you can just as well write it as 1/2. * Add fractions. If two fractions have different denominators, you need to convert them to equivalent fractions that have the same denominator. Only then can you add. * Subtract fractions (same as addition). * Compare fractions, to check which one is larger (same as addition).
