That is called "rationalizing the denominator". It consists of multiplying the numerator and the denominator by specific terms, which include square roots. Examples:* If the denominator is root(2) (that is, the square root of 2), multiply numerator and denominator by root(2).
* If the denominator is root(2) + root(3), multiply numerator and denominator by root(2) - root(3).

What is the best method to write an equation that is vertical and the best method for eliminating a fraction from an equation in point-slope that is to be written in standard form.?
For a vertical line, just write: x = ... (whatever the y-coordinate of any point on the line) To eliminate a fraction, you multiply both sides of the fraction by the denominator. If there are several fractions, you can multiply by the least common denominator (or by any common denominator, for that matter). For "standard form" ... Well, I believe there are several standard ways to write equations for straight lines.
How do you convert fraction to decimal with solution?
You divide the numerator of the fraction by its denominator - using long division (aka the bus-stop method) if required.
When dividing fractions is a reciprocal used by multiplying?
Yes. One method for dividing fractions is to multiply the numerator fraction by the reciprocal of the denominator fraction.
How do you subtract a whole number with a fraction from a whole number?
The recommended method in schools is to write the whole number as a rational fraction with denominator 1, and then proceed as you would for subtracting one fraction from another fraction.
How do you turn a mixed number into a imprpoer fraction?
My students call i the C method. Multiply the denominator times the whole number then add the numerator. Put that over the denominator and it is your fraction. 1 2/3=(3x1+2)/3=5/3

how to get the answer when you need to multiply fractions?
Butterfly or cross multiply method the nominator of the first fraction times the denominator of the second and vise versa.
0.625 in fraction form?
I use this method. place 0.625/1 move decimal place of numerator three places right; follow with denominator. 625/1000 factor 125*5/125*8 eliminate 125; top and bottom 5/8 simplest fractional form
What is a equivalent fraction to 4.6?
Use this method. place 4.6/1 move decimal place of numerator the one place needed and follow with the denominator. 46/10 ( factor ) 2*23/2*5 eliminate 2; top and bottom. 23/5 fully reduced
How can you write Fraction in Simplest form by using prime factorization?
You factor numerator and denominator, and eliminate common factors. For example: 8/12 = (2x2x2) / (2x2x3). Eliminating two 2s from both the numerator and the denominator leaves you with 2/3. Note that this is NOT the most efficient method. Especially for large numbers, Euclid's Algorithm is a much faster way to find the greatest common factor of two numbers.
How can you use a method to order fractions from greatest to least?
by cross multiplying is a easy method to use just multiply numerator from a fraction and denominator from another fraction to get the answer on the left side then you switch sides by denominator multiplying numerator to get the answer on the right side of the fraction from the for example 7/8 and 3/4 7x4=28 for 7/8 and 8x3=24 on 3/4 to prove it 7/8 is larger than 3/4
What is 6 and 4 over 7 as improper fraction?
6 4/7 To convert to an improiper fraction. Multiply the denominator to the coefficient(Big number to the left). Then add the fraction numerator, and place the whole over the denominator. Hence ([7 x 6] + 4) / 7 -> (42 + 4) / 7 => 46/7 The improper fraction. NB THis method is good for all mixed number to improper fraction conversions.
