簡約 4/13of_{2}*3/7-68/91-[ 11/2-12/3 ]

解

簡約

\frac{4}{13} \cdot o \cdot f_{2} \cdot \frac{3}{7} - \frac{68}{91} - [\frac{11}{2} - \frac{12}{3}]

\frac{12 o f _{2} - 68}{91} - \frac{3}{2}

解答ステップ

\frac{4}{13} o f_{2} \frac{3}{7} - \frac{68}{91} - (\frac{11}{2} - \frac{12}{3})

\frac{4}{13} o f_{2} \frac{3}{7} = \frac{12 o f _{2}}{91}

\frac{11}{2} - \frac{12}{3} = \frac{3}{2}

= \frac{12 o f _{2}}{91} - \frac{68}{91} - \frac{3}{2}

結合

\frac{12 o f _{2}}{91} - \frac{68}{91} - \frac{3}{2} : \frac{12 o f _{2} - 68}{91} - \frac{3}{2}

= \frac{12 o f _{2} - 68}{91} - \frac{3}{2}
