Crystal wants to add the fractions 1/16 and 3/18 what is the lowest common denominator of the two fractions?
zhenek [66]

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

Let me know if you have any questions

two similar signs have a scale factor of 5:3. if the larger sign is 45 feet tall . how tall is the small sign?
gavmur [86]
Given that 2 similar signs have a scale factor of 5:3 and the larger sign is 45 ft, then the smaller sign will have the height given by:
scale factor=(height of large sign )/(height of smaller sign)
let the height of smaller sign be x, plugging in the values we get:
5/3=45/x
solving for x we get
3/5=x/45
hence
x=3/5×45
x=27 ft
The height of smaller sign will be 27 ft
