$R = \frac{ \frac{0.1}{0.2} + \frac{0.39}{0.12} }{ \frac{2.1}{1.2} - \frac{0.8}{0.16} }$

$R = \frac{ \frac{ \frac{ \frac{1}{10} }{1} }{5} + \frac{ \frac{ \frac{39}{100} }{3} }{25} }{ \frac{ \frac{ \frac{21}{10} }{6} }{5} - \frac{ \frac{ \frac{4}{5} }{4} }{25} }$

$R = \frac{ \frac{1}{2} + \frac{13}{4} }{ \frac{7}{4} - 5 }$

$R = \frac{ \frac{15}{4} }{ - \frac{13}{4} }$

$R = \frac{15}{ - 13}$

$R = - \frac{15}{13}$
