If the numerator of a fraction is zero, it doesn't need to be converted to a common denominator because its value is actually zero (zero by anything divided is zero), so you should drop it from the equation.

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

What are the rules for subtracting fractions?

You multiply the fractions until the denominators are equal. Then, you subtract.


What is the process of subtracting fractions?

If the denominators are the same, subtract the numerators. If the denominators are different, convert them to equivalent fractions with a common denominator and subtract the numerators.


When adding or subtracting fractions do you change the numerator?

you subtract the numerator but the denominator stays the same.


How are lcm's used in adding or subtracting fractions?

To add and subtract fractions, you need common denominators. To find the common denominator, take the LCM of the denominators you wish to add or subtract.


How do you minnous fractions?

To subtract fractions with like denominators, subtract the numerators , and write the difference over the denominator. Example : Find 45โˆ’25 . Since the denominators are the same, subtract the numerators.


Why does the equivalent fraction make adding and subtracting fractions easier?

You cannot add or subtract fractions with different denominators. If the denominators are different then you need to work with equivalent fractions.


How is finding the LCM revelant when adding and subtracting fractions?

To add and subtract fractions, you need common denominators. To find the common denominator, find the LCM of the denominators you wish to add or subtract.


How is subtracting decimals is like subtracting fractions?

because you subtract the 2 numerators and then 2 denominators right across just like that :)


What do you do when you're going to subtract fractions but the numerator is the same?

Whether the numerators are the same or not, you need to get the denominators to be the same. First, find the least common denominator. Then convert the fractions to equal fractions that use the common denominator. Then you can subtract the fractions by subtracting the numerators. Finally, look for common factors between the numerator and the denominator of the difference in order to put the answer in simplest terms.


How do you subtract mixed fractions when they have the same denominator?

The numerator of the answer is the result of subtracting the numerators of the fractions, and the denominator of the fraction is the same as the common denominator.


How do you subtract improper fractions with different denominators?

It's the same thing as adding or subtracting normal fractions - just make sure both fractions have the same denominators (by either multiplying the denominators or simplifying the fraction - whichever the question needs).


What are the rules in subtracting similar fraction?

If the denominators are the same (which is what I understand by "similar fractions"), just subtract the numerators (the upper part).


How do u subtract fractions?

multiply the fractions until they have common denominators and then subtract them


What does subtracting fractions mean?

It means you have to subtract fractions.

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 so you subtract fractions?

You have to get common denominators and then subtract the biggest numerator (top number) by the smallest, you may have to cnacel the fraction down to get the smallest possible fraction


Can you explain adding and subtracting fractions with like denominators?

When you add or subtract fractions with like denominators, you just add or subtract the numerators and put them over the same denominator. For example, 3/5 - 2/5 = (3 - 2)/5 = 1/5


How do you add and subtract by fractions?

If the fractions have the same denominator, add and subtract the numerators as if the denominators weren't there and put the result over that denominator. Reduce if possible. If the fractions have different denominators, find the LCM of the denominators and convert the fractions to equivalent fractions with like denominators. Then add and subtract the numerators as if the denominators weren't there and put the result over that denominator. Reduce if possible.


When you subtract fractions do you subtract the denominator?

No. If the denominators are the same, you subtract the numerators. If the denominators are different you have to find the least common denominator.


Why are two fractions converted into like fractions?

Because you can't add or subtract fractions that have different denominators. Making them like fractions, by multiplying so the denominators are the same, you can add and/or subtract them.


How do you subtract fractions with unequal denominators?

by finding the common denominator of the fractions


Subtract fractions with unlike denominators?

When you add or subtract fractions with unlike denominators why do you have to find LCM?

Because to add fractions, the denominators must be equal.


How do you subtract fractions with same denominators?

you subtract the numerators, and leeave the denomonators alone
