Read the poem “The Purple Cow,” by Gelett Burgess. The Purple Cow (Reflections on a Mythic Beast Who's Quite Remarkable, at Leas
astraxan [27]
Well, I think, the main point that makes the difference between "Mending Wall" and   “The Purple Cow”  is actually demonstrated by the rhyme. Just read each poem one more time and feel that one of them is readed easily, words matched with each other like a song's lyrics so that you can smoothly go on reading whereas  "Mending Wall" is made with structure of blank verse that emphasises every line and makes reader feel it deeply.

This isn't an English Question but...
What you do first is find the LCD (Least Common Denominator)
You do this by finding the factors of 16 and seeing if they correspond with two.
So you're factors are, (1,16) (2,8) (4,4)
So the LCD is 2. You would then make each fraction over two. Since 1/2 is already over 2 you would make 5/16 over two by dividing by 8.
That gives you .347 or 347/1000
Then you would add each whole number, 24 + 2. This gives you 26 and then add the decimel. 26.347
There is probably a simpler way but here's mine.
