Example: 2/3 and 3/4

The LCD of 3 and 4 is 12.

Multiply the numerator and the denominator of 2/3 by 4 to make 8/12

Multiply the numerator and the denominator of 3/4 by 3 to make 9/12

By finding their lowest common denominator by means of their lowest common multiple

If the fractions do not all have the same denominator, find a common multiple of the denominators (ideally the lowest common multiple) and convert the fractions to equivalent fractions with this denominator. Now with all the fractions with the same denominator, add together the numerators. Finally, reduce the fraction to simplest terms, converting any improper fraction to a mixed number.

Find the lowest common multiple of the denominators and adjust the fractions accordingly

Fractions can only be added or subtracted if the denominators are the same. If the denominators are different, then the fractions need to be made into equivalent fractions with the same denominator. The new denominator can be found simply by multiplying the denominators together, but this can lead to some large fractions with which to work. A better new denominator is the lowest common multiple of (all the) denominators. (Once the new denominator is found, the fractions' new numerators are found by multiplying their current numerator by the new denominator divided by their current denominator to make their equivalent fractions with the new denominator.) Once all the fractions are converted into equivalent fractions with the new denominator then the fractions can be added or subtracted, with the result being simplified (if possible).

The first step in finding the lowest common denominator of two fractions is to multiply the two denominators. Then you see if there are any smaller numbers that are divisible by both denominators.

The first step to take is find the lowest common denominator of the fractions which can be done by finding the lowest common multiple of the numbers.

By finding the lowest common denominator of the fractions.

LCD is the Lowest Common Denominator which is the lowest number into which the denominators of all the fractions will each divide exactly. Each of the fractions can then be converted to an equivalent fraction with the new denominator which then allows the fractions to be added and/or subtracted.

If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators. To add fractions with unlike denominators, rename the fractions with a common denominator. Then add and simplify.

There has to be a set of two or more fractions for a lowest common denominator.

If you mean fractions of 3/4 and 5/8 then the lowest common denominator needed is 8

10 is.
