Question 306396
Set up a ratio. 
Percent means out of 100.
5 is to X as 10 is to 100 (10/100=10%).
{{{5/X=10/100}}}
{{{X=500/10=50}}}
5 out of 50 is 10%.

.
Since it's less that 100%, it has to be less than 1. 
So 4 1/6 can't be right.  
Again, percent means out of 100.
{{{18/100=(2*9)/(2*50)=(cross(2)*9)/(cross(2)*50)=9/50}}}
