Example: 1/30 and 1/42
Their LCD is 210.
Multiply each one by whatever it takes to make 210 in the denominator.
30 x 7 = 210
42 x 5 = 210
1/30 x 7/7 = 7/210
1/42 x 5/5 = 5/210

LCD
How the LCD of two or more fractions could be of use?
Once you find the LCD, convert the fractions to their equivalents and then you can add and/or subtract them correctly.
When adding fractions with unlike denominators it is most helpful if the fractions are renamed using the?
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.
