$$\left(\mathrm{1}−\left(\frac{\mathrm{1}}{\mathrm{3}}+\frac{\mathrm{1}}{\mathrm{4}}\right)\right)×\mathrm{5}\frac{\mathrm{1}}{\mathrm{2}}{m}= \\ $$$$=\left(\mathrm{1}−\left(\frac{\mathrm{4}}{\mathrm{12}}+\frac{\mathrm{3}}{\mathrm{12}}\right)\right)×\frac{\mathrm{11}}{\mathrm{2}}{m}= \\ $$$$=\left(\frac{\mathrm{12}}{\mathrm{12}}−\frac{\mathrm{7}}{\mathrm{12}}\right)×\frac{\mathrm{11}}{\mathrm{2}}{m}=\frac{\mathrm{5}}{\mathrm{12}}×\frac{\mathrm{11}}{\mathrm{2}}{m}= \\ $$$$=\frac{\mathrm{55}}{\mathrm{24}}{m}=\mathrm{2}\frac{\mathrm{7}}{\mathrm{24}}{m} \\ $$
