Answer:
288
Step-by-step explanation:
First, simplify the fraction 3/18 to 1/6, this will help a lot. Then, you just, find the LCM, and you can list out the mutliples to help you
6, 12, 18, 24, 39, 36, 42, 48, 54, 60
16, 32, 48, 64, 80
It would be easiest to do 48
But that’s not exactly what the question is asking
It’s asking the LCM of 1/16 and 3/18
I wanted to show you the other way so you would be able to think of it in a different way which would be easier
You would just list out the multiples again.
18, 36, 54, 72, 90, 108, 126, 135, 153, 171, 189
16, 32, 48, 64, 80, 96, 112, 130, 146, 162, 178, 194
Ok, I give up on that
Let’s just do 16*18 which is 288.
288 is your LCM
Sometimes multiplying is easier and other times listing it out is easier.
I hope this helped
