Answer :

The correct answer is:

11

Explanation:

To find the LCM, we first find the prime factorization of each number:

[tex] 2.2=2\times1.1
\\
\\5=5\times 1 [/tex]

We look for common factors first. There are none, except for 1, which is a factor of every number. Next we multiply the uncommon factors:

2(5)(1.1) = 10(1.1) = 11

The LCM is 11.

Answer:

LCM = 11

Step-by-step explanation:

LCM means least common multiple. We have to find the LCM of two numbers 2.2 and 5.

To get the LCM we will find the factors  of 2.2 and 5 first an then multiply common and uncommon factors.

factors of 2.2 = 2×1.1

factors of 5 = 5 (its a prime number)

Here we have all uncommon factors so we will multiply them.

Now LCM of these numbers = 2×(1.1)×5 = 11

So, the answer is LCM of 2.2 and 5 is 11.
