\dfrac{1}{3} − \dfrac{4}{5} = − \dfrac{7}{15}

\dfrac{1}{3} − \dfrac{4}{5} = − \dfrac{3}{15}

\dfrac{1}{3} − \dfrac{4}{5} = \dfrac{3}{2}

\dfrac{1}{3} − \dfrac{4}{5} = \dfrac{7}{2}

\dfrac{3}{4} − \dfrac{3}{8} = 4

\dfrac{3}{4} − \dfrac{3}{8} = \dfrac{1}{4} 

\dfrac{3}{4} − \dfrac{3}{8} = − \dfrac{3}{4} 

\dfrac{3}{4} − \dfrac{3}{8} =  \dfrac{3}{8}

\dfrac{5}{12} − \dfrac{1}{5} = \dfrac{2}{15}

\dfrac{5}{12} − \dfrac{1}{5} = \dfrac{4}{7}

\dfrac{5}{12} − \dfrac{1}{5} = \dfrac{13}{60}

\dfrac{5}{12} − \dfrac{1}{5} = − \dfrac{2}{15}

\dfrac{4}{7} − \dfrac{2}{5} = \dfrac{6}{35}

\dfrac{4}{7} − \dfrac{2}{5} = \dfrac{2}{35}

\dfrac{4}{7} − \dfrac{2}{5} = \dfrac{34}{35}

\dfrac{4}{7} − \dfrac{2}{5} = -\dfrac{2}{35}

\dfrac{3}{4} − \dfrac{2}{9} = \dfrac{19}{36}

\dfrac{3}{4} − \dfrac{2}{9} = \dfrac{1}{36}

\dfrac{3}{4} − \dfrac{2}{9} = \dfrac{1}{4}

\dfrac{3}{4} − \dfrac{2}{9} = − \dfrac{17}{36}
