is 66 2/3 of "x"
what the dickens is "x"? well. hmmm let us make the mixed fraction an "improper fraction" first
so [tex]\bf 66\frac{2}{3}\implies \cfrac{66\cdot 3+2}{3}\implies \cfrac{200}{3}\\\\
-----------------------------\\\\
494=\cfrac{200}{3}x\implies 494=\cfrac{200x}{3}\implies \cfrac{3\cdot 494}{200}=x[/tex]
