What else can I help you with?
How do you reduce the fraction by the method of prime factors 17-51?
68
How can you tell if a fraction repeats using the denominator's prime factors?
First reduce the fraction to its simplest form. If the denominator has any prime factor other than 2 or 5 then it is a repeating decimal. Otherwise it terminates.
What are the 2 method of finding the prime factor?
Factor trees and factor rainbows.
How do you express the prime numbers in factor tree method?
Since prime numbers only have one prime factor (themselves), factor trees are unnecessary.
What is the difference between prime factorization and factor rainbows?
A factor rainbow is a method to determine a prime factorization.
When you reduce a fraction by prime factorization or by dividing what is that called?
It is called simplification.
What is the simplest form of 85 over 130?
The fraction 85/130 will reduce by a factor of 5 to 17/26and because 17 is prime and will not divide into 26, that is as simple as it gets.
Is a fraction prime when the numerator and the denominator both have 1 as their only common factor?
No, prime refers to whole numbers. In the situation you describe, a fraction is in its simplest form.
When the numerator and denominator of a fraction are relatively prime?
When they have no factor in common, or their HCF is 1.
What is the factor of 3 using factor tree method for middle school?
3 is a prime number. Prime numbers don't have factor trees. The factors of 3 are 1 and 3.
If the numerator of a fraction is a prime number can the fraction be simplified?
If the numerator of a fraction is a prime number, then the fraction cannot be simplified any further if the denominator is not a factor of the numerator. This is because a prime number has only two factors: 1 and itself. Therefore, the fraction is already in its simplest form.
What is a fraction that has no common factors in the numerator or the denominator?
If the numerator and denominator are prime numbers and not equal then they don't have common factors (except 1 which would be a common factor even if the numerator and denominator were prime numbers).
