They can help you find a common denominator by the bottoms one of each fraction if the top ones don't have the same denominator. Then find the simplest or non-simplest denominator. Like when you have 2/7+ 2/3=? Well that equals: 20/21. How you find that out is by finding what 7 and 3 have in common is by using a multiplication table until you reach a number they both equal because 7X3= 21 so that's how you get the bottom number. Then you just add the top and that's how you do fractions and the denominator.
The process of finding a lowest common denominator is the same as finding a least common multiple. Example: 1/30 and 1/42
2 x 3 x 5 = 30
2 x 3 x 7 = 42
2 x 3 x 5 x 7 = 210
210 is the lowest common denominator.

How does knowing factors help you simplify fractions?
Knowing factors will help you find a GCF. To simplify a fraction, divide the numerator and the denominator by their GCF.
How can equivalent fractions help when adding mixed numbers?
It can help by when finding the LCD (Least Common Denominator) you find the least number they have in common then that number is your equivalent fraction.
How can the greatest common factor help you write a fraction in simplest form?
Find the greatest common factor between the numerator and the denominator, then divide the numerator by greatest common factor and then divide denominator by greatest common factor, for a new simplified fraction.
Why are prime factors important?
They can help you to find the Lowest Common Multiple and Highest Common Factor of numbers which is useful when dealing with fractions.
Which choices are common factors of the numerator and denominator of the fraction below Check all that apply. A.12 B.6 C.3 D.2 E.1?
Since we do not know what the fraction is - we cannot help you !
How does knowing factors help you simplify fractions?
Knowing factors will help you find a GCF. To simplify a fraction, divide the numerator and the denominator by their GCF.
What part of the fraction does not change when you add or subtract?
If you find the common denominator for the fractions, then the bottom will stay the same :) BUT sometimes it is diffacult to find the common denominator so you may need help
Find the LCD least common denominator HELP 4x - 3 - 1x?
It is not possible to give a sensible answer to this question. The least common denominator (LCD) refers to a multiple that is COMMON to two or more numbers. You have only one number in the question! 4x - 3 - 1x = 3x - 3.
How can equivalent fractions help when adding mixed numbers?
It can help by when finding the LCD (Least Common Denominator) you find the least number they have in common then that number is your equivalent fraction.
How can the greatest common factor help you write a fraction in simplest form?
Find the greatest common factor between the numerator and the denominator, then divide the numerator by greatest common factor and then divide denominator by greatest common factor, for a new simplified fraction.
How can an understanding prime numbers help find the least common denominator?
Finding the prime factorisation of both denominators makes it easier to find the LCD. Simply make two columns, one for each denominator, and write the prime factors side by side. For each factor, note the larger exponent; then multiply out the list.
How divisibility rules can help you find common factors?
Divisibility rules help you find the factors of a number. Once you've found the factors for two or more numbers, you can find what they have in common. Take 231 and 321. If you know the divisibility rules, you know that they are both divisible by 3, so 3 is a common factor.
What is the common factor of 5 over 6 7 over 9 23 over 27 13 over 18?
The common factors of the denominators are 1 and 3, which won't help you. The least common denominator is 54, which will.
What we know about prime and common factors help us find the of two or more numbers?
greatest common factor, or GCF
How can knowing the greatest common factor and least common multiple help you when you add subtract and multiply fractions?
Knowing the least common multiple of the denominators will help you find a common denominator when adding and subtracting unlike fractions. Knowing the greatest common factor of the numerator and the denominator will help you reduce the fraction if possible.
Why are prime factors important?
They can help you to find the Lowest Common Multiple and Highest Common Factor of numbers which is useful when dealing with fractions.
What we know about prime and common factors help us to find the of two or more numbers.?
The answer depends on what it is of two or more numbers that you wish to find.
