$\left( -\frac{ 7 }{ 12 }\div14 \right)-\frac{ 3 }{ 8 } \times \frac{ 5 }{ 3 }$
Dividing is equivalent to multiplying by the reciprocal$\left( -\frac{ 7 }{ 12 } \times \frac{ 1 }{ 14 } \right)-\frac{ 3 }{ 8 } \times \frac{ 5 }{ 3 }$
Cancel out the greatest common factor $3$$\left( -\frac{ 7 }{ 12 } \times \frac{ 1 }{ 14 } \right)-\frac{ 1 }{ 8 } \times 5$
Cancel out the greatest common factor $7$$\left( -\frac{ 1 }{ 12 } \times \frac{ 1 }{ 2 } \right)-\frac{ 1 }{ 8 } \times 5$
Calculate the product$\left( -\frac{ 1 }{ 12 } \times \frac{ 1 }{ 2 } \right)-\frac{ 5 }{ 8 }$
Multiply the fractions$\left( -\frac{ 1 }{ 24 } \right)-\frac{ 5 }{ 8 }$
Remove unnecessary parentheses$-\frac{ 1 }{ 24 }-\frac{ 5 }{ 8 }$
Calculate the difference$\begin{align*}&-\frac{ 2 }{ 3 } \\&-0.\overset{ \cdot }{ 6 } \end{align*}$
