namely how many times does 2⅓ go into 18.
well, let's firstly convert the mixed fraction to "improper" and then get the quotient.
[tex]\bf \stackrel{mixed}{2\frac{1}{3}}\implies \cfrac{2\cdot 3+1}{3}\implies \stackrel{improper}{\cfrac{7}{3}}
\\\\\\
\cfrac{\quad 18\quad }{\frac{7}{3}}\implies \cfrac{\quad \frac{18}{1}\quad }{\frac{7}{3}}\implies \cfrac{18}{1}\cdot \cfrac{3}{7}\implies \cfrac{84}{7}\implies 12[/tex]
