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 :)
The least common multiple of the denominators is called the least blank blank blank?
It is: the 'least common denominator'
What are fractions called when the numerator is greater than or equal from the denominator?
improper fractions
How can using the GCF and LMC help you you add subtract and multiply fractions?
In order to add or subtract fractions, the denominator (bottom number) has to be the same. In order to make it the same, you find the LCM and multiply the fraction by whatever is necessary to make the denominator the LCM. FOR EXAMPLE: 1/3 + 2/5 The LCM of 3 and 5 is 15. To make the 3 in 1/3 15, you multiply the whole fraction by 5 over 5 (it simplifies to 1 so you aren't really changing the fraction by multiplying it by 1). 1/3 * 5/5 is 5/15 You multiply 2/5 times 3 over 3 using the same principle 2/5 * 3/3 is 6/15 NOW you can add 5/15 and 6/15 to get 11/15.

What is the common denominator of 4 and 14?
Assuming those are denominators of fractions you wish to add or subtract, you can use any common multiple of 4 and 14; the Lowest Common Multiple (LCM), often called the Lowest Common Denominator (LCD) especially when when referring to the denominators of fraction, provides the smallest numerators. For 4 and 14, the LCM is 28.
The least common multiple of two or more denominators?
This is called the least common denominator.
A common multiple of two or more denominators is called a?
common denominator
The smallest common multiple of two or more denominators is called?
the least common denominator
How can you add similar and dissimilar fractions?
Adding similar fractions is easy, but adding dissimilar ones requires an additional step. Before you begin, you must know a few important key terms. First, the number on the top of a fraction is called the numerator, while the number on the bottom of a fraction is called the denominator. Similar fractions have the same denominator, also called a common denominator. To add dissimilar fractions (fractions with different denominators), you must first convert the fractions so that the denominators are the same.
What are like fractions?
Fractions with the same denominators are called like fractions. eg: 2/5 and 4/5 eg: 6/7and 9/7
What is the least common multiple in addition fraction?
When adding unlike fractions, it is necessary to find the LCM of the denominators and convert them to it.. In this instance, it's called the least common denominator, but it's the same process.
The least common multiple of the denominators is called the least blank blank blank?
It is: the 'least common denominator'
What are fractions that have the same denominator called?
Like Fractions
What is a common denominator?
Sometimes fractions have different denominators. These are called unlike fractions. When adding or subtracting fractions with unlike denominators, it is necessary to find a common denominator to get the correct answer. This is the same process as finding the least common multiple. Example 1/30 + 1/42 Factor them. 2 x 3 x 5 = 30 2 x 3 x 7 = 42 Combine the factors, eliminating duplicates. 2 x 3 x 5 x 7 = 210, the lowest common denominator.
What are fraction that have same denominator called?
They are called like fractions.In order to add or subtract fractions you will usually need to convert them to like fractions. Then you simply add or subtract the numerators (as required) to form the numerator of the answer. The same (or common) denominator is the denominator of the answer. You may need to simplify the resulting fraction.
