What are the differentiate of GCF LCM and LCD?
The greatest common factor, or GCF, is the largest number that can divide evenly with no remainder into all the members of a given set of numbers. The least common multiple, or LCM, is the smallest number that all the members of a given set of numbers can divide into evenly with no remainder. The lowest common denominator, or LCD, is essentially the same thing as the LCM except the numbers being compared are the bottom parts of fractions.
What is the LCD of 11 and 18?
The LCM of these numbers is 198. (LCD is just the LCM of the denominators of fractions.)
Find the LCD then add or subtract?
To add or subtract fractions the denominators must be the same - then the numerators are added or subtracted with the denominator being kept the same.When adding or subtracting fractions with different denominators, the fractions must first be converted into equivalent fractions with the same denominator and then the (new) numerators can be added or subtracted as required.For the denominator for these equivalent fractions, the original denominators can all be multiplied together, but this can lead to having to work with very large numbers; a better choice for the denominator is the smallest number that all the denominators divide into, their Least Common Multiple (LCM) - this is is then used as the denominator for the equivalent fractions and is called the Least Common Denominator (LCD) of the fractions.First you find the LCD okay??? Then you have to add or subtract. What they mean by that is that once you've found your lcd add or subtract..xx hope i helped :)
What is the LCD of 6 8 16?
Assuming you mean the LCM (Least Common Denominator of 2 fractions is the LCM of the denominators, which for 7/1 and 16/1 is 1), the answer is 112.
How can the greatest common factor and least common multiple help you work with fractions?
Finding the GCF of the numerator and the denominator of a fraction and dividing them both by it will give you the simplest form of that fraction. Finding the LCM of unlike denominators and converting them to it will make it possible to add and subtract unlike fractions.
What is the LCD for fractions?
The LCD for fractions is the LCM (least common multiple) of all of the denominators.
What is common between he LCM and LCD?
The same process can be used to find them. They're essentially the same thing, except the LCD is used with fractions.

Difference LCD and LCM?
The function of the numbers in question. The process is the same. When comparing two whole numbers, we call it the LCM. When comparing two fractions, we call it the LCD.
What is the LCD of 11 and 18?
The LCM of these numbers is 198. (LCD is just the LCM of the denominators of fractions.)

How does the concept of LCM relate to fractions?
When you are adding or subtracting fractions with unlike denominators, you need to find a least common denominator, or LCD. The process is the same as finding an LCM between two integers.
Explain how comparing fractions with like denominators differs from comparing fractions with unlike denominators?
Because when you compare fractions with the same denominators, you do not have to find the least common denominator (LCM or LCD).
How do you add and subtract by fractions?
If the fractions have the same denominator, add and subtract the numerators as if the denominators weren't there and put the result over that denominator. Reduce if possible. If the fractions have different denominators, find the LCM of the denominators and convert the fractions to equivalent fractions with like denominators. Then add and subtract the numerators as if the denominators weren't there and put the result over that denominator. Reduce if possible.
How do you find the LCM multiple for two fractions?
The LCM is used for integers, not fractions. If you're trying to add unlike fractions, take the LCM of the denominators (known in this case as the least common denominator, or LCD), convert the fractions and proceed.
How do you find the sum of 5 over 12 and 9 over 6?
5/12 + 9/6The least common multiple (LCM or common denominator) of 12 and 6 is 12 so bring both fractions to the same denominator: 5/12 + 18/12Add the numerators, the denominator is the LCM: 23/12Answer = 23/125/12 + 9/6The least common multiple (LCM or common denominator) of 12 and 6 is 12 so bring both fractions to the same denominator: 5/12 + 18/12Add the numerators, the denominator is the LCM: 23/12Answer = 23/125/12 + 9/6The least common multiple (LCM or common denominator) of 12 and 6 is 12 so bring both fractions to the same denominator: 5/12 + 18/12Add the numerators, the denominator is the LCM: 23/12Answer = 23/125/12 + 9/6The least common multiple (LCM or common denominator) of 12 and 6 is 12 so bring both fractions to the same denominator: 5/12 + 18/12Add the numerators, the denominator is the LCM: 23/12Answer = 23/12
Can you add numbers with different numerators?
Yes, 'fractions' with different numerators can be added, but not with different denominators. In the case where you have different denominators, you must find the LCM (lowest common multiple).
