The LCM is used for integers, not fractions. If you're trying to add unlike fractions, take the LCM of the denominators (known in this case as the least common denominator, or LCD), convert the fractions and proceed.
The LCM is 30.
The LCD for fractions is the LCM (least common multiple) of all of the denominators.
Finding an LCM will help when you want to add and subtract fractions.
The LCM of 30 and 25 is 150.
The LCD of two fractions is the same as the LCM of their denominators.
The LCM refers to integers, not fractions.
Finding the LCM will make adding and subtracting fractions easier.
The HCF helps when reducing fractions. The LCM helps when adding or subtracting fractions.
The LCM is used for integers, not fractions. If you're trying to add unlike fractions, take the LCM of the denominators (known in this case as the least common denominator, or LCD), convert the fractions and proceed.
Use the GCF to reduce fractions. Use the LCM to add and subtract unlike fractions. Carpenters work with fractions a lot.
The LCM applies to whole numbers, not fractions.
The LCM refers to whole numbers, not fractions.
The LCM is 30.
Example 7/30 + 11/42 Find the LCM of 30 and 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 LCM Convert the fractions to common denominators. 49/210 + 55/210 = 104/210 or 52/105
When adding fractions, you want to make sure that the denominators are the same. It's the same process as the LCM.
The LCM of 14 and 42 is 42.
