Answer 5

LCD of 6, 12 and 18

Two ways:
1) make list of multiples
2) factoring

1) make list of multiples
6: 6 12 18 24 30 36
12: 12 24 36
18: 18 36

36 is the first number that appears in all 3 lists

2) factoring
write each number as a product of its factors
6: 2*3
12: 2*2*3 = 2^2*3
18: 2*3*3 = 2*3^3

construct the LCD by taking the highest power of each unique factor encountered
2^2*3^3 = 4*9=36

Answer 6

So, multiply 1/6 by 6/6 to put it over a denominator of 36. Multiply 5/12 by 3/3 to put it over a denominator of 36. Multiply 11/18 by 2/2 to put it over a denominator of 36.
