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

How do you find an equivalant fraction?

A fraction is equivalent to another if the ratio of the numerator and denominator is the the same in both. To find an equivalent fraction, multiply or divide the numerator and denominator by the same ammount.


When you multiply each numerator of a fraction by the denominator of another fraction in a proportion you?

You get the same answer both times.


When you multiply a denominator do you multiplicate the numerator?

That depends what you want to do. If you multiply both the numerator and the denominator by the same number, you get another fraction that stands for the same number - an equivalent fraction. For example, if you have the fraction 1/2, you multiply top and bottom by 2, to get 2/4. 2/4 is simply another name for 1/2.


How can we find the same fraction as another one?

Multiply the numerator and the denominator by the same integer.


What does Cross multiplication mean?

Cross multiplication is when you multiply the denominator of a fraction by the numerator of another fraction. Before you cross multiply you want to see if you can simply the fractions.


How do you simplify a fraction then write it as a decimal?

simply divide the numerator and denominator by two. if they are not even, find another multiple that fits both the numerator and denominator. once you have simplified the fraction, just turn the denominator into 100 (make sure you multiply or divide only) then multiply or divide the same number by the numerator, then you divide it by 100 and you get your answer!!!!!


What is the invert and multiply rule in mathematics?

You may be referring to the rule for dividing fractions. To divide one fraction by another, you invert the second fraction (exchange numerator and denominator), and multiply instead.


What is another equivalent fraction for 4 over 28?

equivalent of 4 over 28 is 1 over 7. you divide by 4 both numerator and denominator or multiply by the same number both numerator and denominator


How do you find find equivlant fractions?

Multiply both the numerator and the denominator of the fraction you already have by the same number, and you'll get another fraction that's equivalent to it.


How do you find a fraction with the same denominator?

Simply change the numerator and you will have another - different - fraction wit the same denominator.


Why can you multiply a fraction by another fraction that has the same numerator and denominator and get a fraction that names the same amount as the original fraction?

You cannot because it is not true - unless the fraction is 0/n (for any n) or n/n = 1.


Is there such thing as a fraction with 100 as the denominator?

Any real number can be the denominator in a fraction. A fraction is a way of expressing one number (the numerator, the "top" number in a fraction) by another (the denominator, "bottom number.") So it is possible to have a denominator of 100.


How do you convert from one unit to another in a different system?

Write the conversion as a fraction. Then multiply the numerator and denominator across, then cancel any units that are both top and bottom.


Describe how finding the greatest common factor of the numerator and denominator of a fraction can help reduce the fraction?

5/7 is a fraction in its simplest form. To create an equivalent fraction it is necessary to multiply both the numerator and the denominator by the same integer. The opposite is also true. To reduce an equivalent fraction to its simplest form, it is necessary to divide both the numerator and the denominator by the same integer. 20/28 is an equivalent fraction of 5/7. It is possible to reduce 20/28 to 10/14 by dividing both the numerator and the denominator by 2, but that is not the simplest form. 10/14 can be reduced to 5/7 by dividing both the numerator and the denominator by 2 again. To ensure that an equivalent fraction is reduced to its simplest form, it is necessary to divide by the largest factor that is part of both of them. Another term for this the Greatest Common Factor, or GCF.


What happens when you add subtract multiply and divide fractions?

The result (which should be simplified) is another fraction of some kind: * a proper (or vulgar fraction) with the numerator (top number) less than the denominator (bottom number); * an improper fraction with the numerator greater than the denominator which can be converted into a mixed number; or * an integer (whole number).


How do you didvide a fraction by a fraction?

To divide a fraction by another fraction, you multiply by the reciprocal - that is, in the second fraction you exchange numerator and denominator, while at the same time changing the division to a multiplication.Example: 5 divided by one-and-a-half5 / (1 1/2) = 5 / (3/2) = 5 x (2/3)To divide a fraction by another fraction, you multiply by the reciprocal - that is, in the second fraction you exchange numerator and denominator, while at the same time changing the division to a multiplication.Example: 5 divided by one-and-a-half5 / (1 1/2) = 5 / (3/2) = 5 x (2/3)To divide a fraction by another fraction, you multiply by the reciprocal - that is, in the second fraction you exchange numerator and denominator, while at the same time changing the division to a multiplication.Example: 5 divided by one-and-a-half5 / (1 1/2) = 5 / (3/2) = 5 x (2/3)To divide a fraction by another fraction, you multiply by the reciprocal - that is, in the second fraction you exchange numerator and denominator, while at the same time changing the division to a multiplication.Example: 5 divided by one-and-a-half5 / (1 1/2) = 5 / (3/2) = 5 x (2/3)


how can you change from one equivalent fraction to another?

To convert a fraction to an equivalent fraction, you multiply, or divide, both parts (numerator and denominator, that is, top and bottom), by the same non-zero number. Thus, for example, if you have a fraction 3/5, you can multiply top and bottom by 2 to get 6/10, or by 3 to get 9/15, etc.


A fraction should be reduced when?

When the numerator and denominator have another common factor besides ' 1 '.


How do you get a fraction of another fraction?

To get a fraction of another fraction you have to multiply the fractions. To multiply fractions, just use this simple algorithm: Step 1-Turn all whole numbers and mixed numbers into improper fractions. Step 2-Multiply the numerators of the 2 fractions. The answer to that problem will be the numerator of the answer. Step 3-Multiply the denominators of the 2 fractions. The answer to that problem will be the denominator of the answer. Step 4-Reduce.


What is the fraction 8 over 25 as a percent?

To convert a fraction to a percent, you first divide the numerator by the denominator. And then multiply by 100, which moves your decimal point two places to the right.Another way to do it, or check your answer, is to make the fraction equivalent to a denominator of 100. So if you were to convert 8/25 to X/100, your new numerator would be the percentage.


What the algorithm for dividing 2 fraction?

If you mean to divide one fraction by another, the easiest is to multiply your numerator fraction by the reciprocal of your denominator fraction. For example, if: x = (a / b) / (c / d) then: x = (ad)/(bc)


What is thirteen over three divided by eight over three?

To divide one fraction by another, you multiply the first fraction by the reciprocal of the second - that is, you exchange numerator and denominator in the second fraction, then multiply. Therefore, 13/3 divided by 8/3 is the same as 13/3 times 3/8.


Why do you have to multiply or divide both the numerator and denominator of a fraction to find equivalent fraction?

So you can answer question 1 in your homework. Any number times 1 is equal to the original number. When we simplify a fraction or change a fraction to find a common denominator so we can add or subtract if from another fraction we do not want to change it's value. We multiply ( or divide it ) it by one essentially. Remember 5/5 = 2/2 = 7/7 = 1.


What is a conversion factor?

A fraction in which the same quantity is expressed one way in the numerator and another way in the denominator.


What a product of the numerator of on fraction and the denominator of another fraction?

Near enough what you describe in the question - except that you say "on" instead of "one". It has no special name.
