If the GCF of 11 and x is 1 and the LCM of 11 and x is 99, x= 9.
11 is 1 greater than 10 10 is 1 smaller than 11
13
11 is the LCM of 1 and 11.
(5/6) * (1/10) + (2/3) / (4/11) = (5/6) * (1/10) + (2/3) * (11/4)= (1/12) + (11/6) = 1/12 + 22/12 = 23/12 or 111/12(5/6) * (1/10) + (2/3) / (4/11) = (5/6) * (1/10) + (2/3) * (11/4)= (1/12) + (11/6) = 1/12 + 22/12 = 23/12 or 111/12(5/6) * (1/10) + (2/3) / (4/11) = (5/6) * (1/10) + (2/3) * (11/4)= (1/12) + (11/6) = 1/12 + 22/12 = 23/12 or 111/12(5/6) * (1/10) + (2/3) / (4/11) = (5/6) * (1/10) + (2/3) * (11/4)= (1/12) + (11/6) = 1/12 + 22/12 = 23/12 or 111/12

The Least Common Multiple (LCM) for 11 1 is 11.
The Least Common Multiple (LCM) of 1 and 11 is 11.
The LCM is: 12
The GCF is 1. The LCM is 10. The LCD is related to the LCM.

11 is prime, so it won't have any factors in common with 12. In this case multiply them and get 132, the LCM.There are many methods of finding the LCM of two numbers.Method 1:Method of prime factorization is one of the methods.Prime factorization of 11 = 11(11 is prime)Prime factorization of 12 = 2x2x3Is there anything common in the factorization of both numbers? Nothing, so in this case we multiply 11 and 12 to get our LCM: 11 x 12 =132.Method 2:There is a relation between LCM and GCF of two numbers a and b:LCM(a,b) x GCF(a,b) = Product of a and bSince 11 and 12 are consecutive numbers then their GCF is 1 and product of 11 and 12 is 132.Putting the values in the relation we get:LCM(11,12) x 1 = 132LCM(11,12) = 132/1 = 132Not every time we need to go through these methods, here is a trick to remember: LCM of two consecutive numbers is equal to their product.11 and 12 are consecutive numbers so their LCM is 11 x 12 = 132.
LCM(1, 12, 34) = 204.
(11/12) / (1/11) = (11/12) x (11/1) = 121/12 = (10 and 1/12) = 10.08333 of them (rounded)
