It is false.
I got this information from 2 brainlys, 1 other answers, and people said this is wrong so its obviously the opposite.
I also just did it on apex.

How do you rationalize a denominator?
You multiply the numerator and the denominator by the same expression - and do it in such a way that the denominator becomes rational.Example 1: The denominator is square root of 5, which I will call root(5). If you multiply top and bottom by root(5), the denominator will become rational. Example 2: The denominator is root(2) + root(3). If you multiply top and bottom by root(2) - root(3), then the denominator will become rational.
How do you eliminate fractions in an equation?
Multiply both sides ofthe equation by the 'denominator' of the fraction.
How do you make a mixed number in to an improper fraction?
The mixed number consists of a whole number and a fraction. Multiply the denominator of the fraction portion by the whole number and to this product add the numerator of the fraction portion. This value is the numerator of the new improper fraction. The denominator of the new improper fraction is the same as the denominator of the original fraction portion of the mixed number.
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!!!!!
How do you convert mixed numbers to fractions?
To convert an improper fraction to a mixed number, divide the denominator into the numerator. The answer is the whole number. Put any remainder over the original denominator to create the fraction part.
To rationalize a denominator that has more than one term you multiply the fraction by bb where B is the conjugate of the numerator?
No, that is not what you do.
What does it mean to rationalize a denominator?
Sometimes the denominator is an irrational or complex number (depending on the level that you are at). Rationalising the denominator requires to multiply both the numerator and denominator of the fraction by a suitable number - usually the conjugate - so that when simplified, the denominator is rational - normally an integer.
How do you simplify a complex fraction?
You multiply the numerator and the denominator of the complex fraction by the complex conjugate of the denominator.The complex conjugate of a + bi is a - bi.
How do you rationalize the denominator of a radical expression that has two terms in the denominator?
You multiply the numerator and the denominator by the "conjugate" of the denominator. For example, if the denominator is root(2) + root(3), you multiply top and bottom by root(2) - root(3). This will eliminate the roots in the denonimator.
Why rationalize a denominator?
You rationalize a denominator in a question because having a irrational root makes it harder to work with then a irrational in the numerator. I've never heard anyone question it and it is not hard to remove an irrational root. All you have to do is multiply the top and bottom by its conjugate.
What's first step is to multiply top and bottom of the conjugate of the denominator?
Either: when given a fraction with a surd as the denominator, rationalising the denominator; Or, when given a fraction with a complex denominator, to make the denominator real.
How do you simplify complexed fractions?
You multiply the numerator and the denominator of the complex fraction by the complex conjugate of the denominator.The complex conjugate of a + bi is a - bi.
How do you rationalize a denominator?
You multiply the numerator and the denominator by the same expression - and do it in such a way that the denominator becomes rational.Example 1: The denominator is square root of 5, which I will call root(5). If you multiply top and bottom by root(5), the denominator will become rational. Example 2: The denominator is root(2) + root(3). If you multiply top and bottom by root(2) - root(3), then the denominator will become rational.
How do you do a fraction times a fraction?
you multiply the numerator by the numerator and the denominator by the denominator.
What do you do to the numerator in a lowest common denominator problem?
Multiply the numerator of the fraction by the same amount that you multiply the denominator of that fraction.
How do you rationalize denominator surds?
An example may help. If you have the fraction 1 / (2 + root(3)), where root() is the square root function, you multiply top and bottom by (2 - root(3)). If you multiply everything out, you will have no square root in the denominator, instead, you will have a square root in the numerator. If the denominator is only a root, eg root(3), you multiply top and bottom by root(3).
What does two thirds of a fraction equal?
Multiply the numerator of the fraction by 2 to get the new numerator. Multiply the denominator of the fraction by 3 to get the new denominator. Answer = (new numerator)/(new denominator).
