the least common denominator

the least common denominator

When adding and subtracting unlike fractions, find the LCM of the denominators and convert them to it. In this case, it's called the least common denominator, but it's the same process.

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 :)

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.

Fractions with the same denominators are called like fractions. eg: 2/5 and 4/5 eg: 6/7and 9/7

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.

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.
