What is the numerator with 32 as the denominator?
It can be any number: integer, rational, real, complex.
What is nominator and denominator?
In a fraction, the numerator represent the part out of the denominator which represents the total. Neither need be rational (or even real).
What is prime factorization in fractions?
You use a factor tree, for the 2 denominators. Yes that is correct the answer on the top but it says 2 denominators. This is the real correct way To do Prime Factorization in fractions first prime factorization the numerator and then the denominator. then put the prime factorization of the numerator on top and put the prime factorization of the denominator on the bottom like fractions.
Why do you multiply by the complex conjugate?
Whenever a complex number (a + bi) is multiplied by it's conjugate (a - bi), the result is a real number: (a + bi)* (a - bi) = a2 - abi + abi - (bi)2 = a2 - b2i2 = a2 - b2(-1) = a2 + b2 This is useful when dividing complex numbers, because the numerator and denominator can both be multiplied by the denominator's conjugate, to give an equivalent fraction with a real-number denominator.
What algorithms will produce the correct result for the sum a b where a and b each represent rational numbers?
You are basically asking how to add two fractions together: Assuming your rational numbers are in the form of a fraction with a numerator over a denominator (could be stored as an ordered pair, or an ordered triple [for mixed numbers]). If the numbers are mixed numbers the first step is to convert them to improper fractions. To add rational numbers the denominators must be the same. If they are not the same then the fractions need to be converted into equivalent fractions with the same denominator. Then the fractions are added by adding together the numerators Finally the result is simplified by dividing the numerator and denominator by their Highest Common Factor (HCF). If the numerator is greater than or equal to the denominator, then the fraction is converted to a mixed number. To convert a mixed number to an improper fraction, the new numerator is the whole number multiplied by the denominator plus the original numerator; the new denominator is the original denominator. To find the new denominator for equivalent fractions it is best done by finding the lowest common multiple (LCM) of the denominators. To find the LCM, there are various methods, but I would suggest* using the fact that the product of the HCF and LCM of two number is the product of those two numbers; then the LCM is the product of the numbers divided by their HCF. The HCF of two numbers is easily found by using Euclid's method: to find the HCF of two numbers a and b: 1) find the remainder (r) of the first number (a) divided by the second (b) 2) If the remainder is 0, the HCF is the second number; otherwise 3) replace the first number (a) by the second number (b) 4) replace the second number (b) bu the remainder (r) 5) repeat from step 1. (If a < b the first time through the algorithm will swap a and b so that a > b.) There is no need to check for denominators being the same as the LCM will work out to be the current denominator. To convert a fraction with one denominator to an equivalent fraction with a new denominator, the new numerator is found by multiplying the old numerator by the new denominator and divide by the current denominator (which is the same as finding out how many times the current denominator divides into the new denominator and multiplying the numerator by this). I To do the addition, the numerators are added together and the denominator is kept. To simplify the fraction find the HCF of the numerator and denominator and divide each by this HCF. (No real need to check for HCF = 1 → fraction already as simple as possible but dividing by 1 will leave the numerator and denominator as they are!) To convert an improper fraction to a mixed number, divide the numerator by the denominator to get a whole number quotient and a remainder. The remainder is the numerator over the denominator for the fraction of the mixed number with the quotient as the whole number. If the whole number is zero, then the fraction is a proper fraction; if the remainder is zero, then the fraction is a whole number. ----------------------- * This suggestion means the LCM function becomes: LCM(a, b) = a * b / HCF(a, b) And only the HCF function need be worked out in a full algorithm. For two numbers Euclid's method provides an easy function. For more than 2 numbers I would use the prime factorization method.

Is 25 5 fraction a real number?
All fractions (with whole numbers in the numerator and the denominator - zero in the denominator is not allowed) are rational numbers, and therefore also real numbers.
How do your turn a fraction into a real number?
You divide the top number (numerator) by the bottom number (denominator) and you will get a number.
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 are a numerator and denominator similar?
They are elements of of a set which may consist of integers, real or complex numbers, polynomial expressions, matrices.
Classify the number as rational or irrational?
If you can express a real numbers as a fraction (with integers in the numerator and the denominator), then it is rational. Otherwise it is irrational.
Where do you use GCF in real life?
When reducing fractions to their simplest form the greatest common factor of their numerator and denominator must be found.
Is a method of dividing a factor in the numerator by the same factor in the denominator?
Yes, that is a method. The real question is, though, if it's a correct method...(trollface)
How do you do arithmetic complex math?
Addition and subtraction: add (or subtract) the real parts, then add (or subtract) the imaginary parts. Multiplication: treat just like multiplying binomials (like with a variable x).After multiplying, convert any i² terms to -1.Division: multiply both numerator and denominator by its conjugate, which will make the denominator a real, then divide real part by denominator, and then divide imaginary part by denominator.
What is the multiplicative inverse of 4 plus 3i?
Use the rules of division for complex numbers. Just divide 1 / (4 + 3i). This requires multiplying numerator and denominator of this fraction by (4 - 3i), to get a real number in the denominator.
