It means find the LCM of the denominators. In order to add and subtract fractions with unlike denominators, it is necessary to convert them to equivalent fractions with a common denominator.

Example: 1/4 + 1/6

The LCM of 4 and 6 is 12.

1/4 = 3/12

1/6 = 2/12

It is the least common multiple of the two fractions' denominators. To add or subtract a pair of fractions it is necessary to rename them using the common denominator.

How do I find a common denominator in a fraction?

By finding the lowest common multiple of the denominators


How do you change a fraction so they have the same denominator?

First, find a common denominator for the two (or more) fractions. Then, for each fraction, multiply numerator and denominator by the same number (different numbers for different fractions, though), to convert to the common denominator.


How do you subtart fractions?

subtract? Find a common denominator (LCD is preferred). Convert each fraction to an equivalent fraction with the LCD. Add numerators, keep LCD as new denominator. Reduce the fraction.


How are equivalent fractions used when subtracting unlike fractions?

First you find a common multiple of the denominators. The least common denominator is handy but not essential. This number will be the denominator of the answer - before simplification.For both fractions find an equivalent fraction whose denominator is this common denominator.Carry out the subtraction on the new numerators to give the numerator of the answer.Simplify the result for the final, simplified answer.First you find a common multiple of the denominators.

What does write each fraction in the simplest form mean?

To reduce a fraction to its simplest form, find the GCF of the numerator and the denominator and divide them both by it. If the GCF is 1, the fraction is in its simplest form.
