What is LCM of .99 and 1.35?

The concept of LCM is appropriate only for integers. Once you introduce fractions, any number is divisible by a non-zero fraction and so the concept loses all meaning.


How can you find the LCM of two fractions?

The concept of LCM is not applicable to fractions. This is because all numbers are evenly divisible by all non-zero numbers and all numbers are multiples of all non-zero numbers.


What is the LCM for 99 and 1.35?

The concept of LCM makes sense for integers only. Once you introduce the concept of fractions LCM makes no sense because any non-zero number can be expressed as a multiple of any other non-zero number.

How do you find the LCM multiple for two 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.
