Answer:
10
Step-by-step explanation:
I find it easier to work with decimals, so I'll start by converting to decimal form:
5 1/2 = 5.5
11/20 = 0.55
So the new version of this equation is 5.5/x=0.55
Now I can rearrange and solve for x:
[tex]\frac{5.5}{x}=0.55\\ 5.5=0.55x\\\frac{5.5}{0.55}=x\\ 10=x[/tex]
