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.
It is usually referred to by using letters to indicate which lines rhyme; lines designated with the same letter all rhyme with each other. So it would be AA,BB
