A.) m : n + p = [ - \frac{3}{8} : \frac{25}{100} ] +  \frac{25}{3} => [ - \frac{3}{8}  \frac{100}{25} ] +  \frac{25}{3} => - \frac{3}{2}  \frac{25}{3} =>  \frac{41}{6}

b.) ( n : m ) x p = (  \frac{25}{100} - \frac{3}{8} ) x  \frac{25}{3} => (  \frac{25}{100} x   \frac{8}{-3} ) x  \frac{25}{3} =>  \frac{2}{-3}  \frac{25}{3} =>  \frac{50}{-9}
