You get $\displaystyle\frac{{2}}{{3}}\cdot{\left(\frac{{1}}{{5}}\cdot\frac{{5}}{{2}}\right)}\usepackage{cmbright}\Huge\$ by using the associative property to regroup. Then you get $\displaystyle\frac{{2}}{{3}}\cdot{\left(\frac{{5}}{{2}}\cdot\frac{{1}}{{5}}\right)}\usepackage{cmbright}\Huge\$ or $\displaystyle{\left(\frac{{1}}{{5}}\cdot\frac{{5}}{{2}}\right)}\cdot\frac{{2}}{{3}}\usepackage{cmbright}\Huge\$ depending on which multiplication you apply the commutative property to. Neither of these resulted in $\displaystyle\frac{{1}}{{5}}\cdot{\left(\frac{{2}}{{3}}\cdot\frac{{5}}{{2}}\right)}\usepackage{cmbright}\Huge\$ .
