Both A and B are false. $\displaystyle-{2.7}\usepackage{cmbright}\Huge\$ is to the right of $\displaystyle-{4.6}\usepackage{cmbright}\Huge\$ on a number line, so $\displaystyle-{2.7}>-{4.6}\usepackage{cmbright}\Huge\$ . Negative numbers are always to the left of positive numbers on a number line, so $\displaystyle-{7.3}<{1.2}\usepackage{cmbright}\Huge\$ . The correct answer is C and D.
