3+(1/5)+2+(1/(15))=5+(1/5)+(1/(15))=5+(1^(×3) /5^(×3) )+(1/(15))=  =5+(3/(15))+(1/(15))=5+((3+1)/(15))=5+(4/(15))=5(4/(15))
$$\mathrm{3}+\frac{\mathrm{1}}{\mathrm{5}}+\mathrm{2}+\frac{\mathrm{1}}{\mathrm{15}}=\mathrm{5}+\frac{\mathrm{1}}{\mathrm{5}}+\frac{\mathrm{1}}{\mathrm{15}}=\mathrm{5}+\frac{\mathrm{1}^{×\mathrm{3}} }{\mathrm{5}^{×\mathrm{3}} }+\frac{\mathrm{1}}{\mathrm{15}}= \\ $$$$=\mathrm{5}+\frac{\mathrm{3}}{\mathrm{15}}+\frac{\mathrm{1}}{\mathrm{15}}=\mathrm{5}+\frac{\mathrm{3}+\mathrm{1}}{\mathrm{15}}=\mathrm{5}+\frac{\mathrm{4}}{\mathrm{15}}=\mathrm{5}\frac{\mathrm{4}}{\mathrm{15}} \\ $$
