Step-by-step explanation:
Put these numbers into their prime factors.
18: 2 * 3 * 3
27: 3 * 3 * 3
12: 2 * 2 * 3
The LCM must have
two 2s
Three 3s
That's it
2*2 * 3 * 3 * 3
LCM = 108
648 might be a multiple of the three, but it's not the smallest one.
108 = 27 * 4
108 = 18 * 6
108 = 12 * 9

Answer:
The answer to this equation is 7.5
Step-by-step explanation:
What I did is started with PEMDAS:
6÷2 (1 + 2) ÷4 (4 + 5) ÷ 6
^ ^
(3) (9)
Now the 3 and the 9 are what are in the ()
6÷2 = 3... 3 (3) = 9.
9 ÷ 4 = 5.
The 9 from earlier is still in parenthesis...
Take 5 and the 9 in parenthesis and multiply (If a single number is in (), It means to multiply anyway)
5 (9) = 45
The Final Step is to divide by 6
45 ÷ 6 = (FINAL) 7.5
