If the numbers 19/36, 5/11, 12/25, 6/11, and 8/18 were arranged from least to greatest, which number would be in the middle?
Choose the correct choice from the following answers
A) 19/36 B) 12/25 C) 6/11 D) 5/11 E) 8/18
All numbers are about 1/2 so you can separate those are bigger from those are smaller:   19/36 bigger than 18/36=1/2   12/25 smaller than 12/24=1/2   6/11 bigger than 6/12=1/2   5/11 smaller than 6/12=1/2   8/18=4/9 smaller than 4/8=1/2   now you have to choose 12/25, 5/11 or 4/9.   you compare 4/9 and 5/11: the least common multiple between 9 and 11 is 99---&gt; 44/99 &lt; 45/99   you compare now 5/11 and 12/25: the LCM is  25*11=
