Question

$$- \frac{ 1 }{ 4 } /(- \frac{ 3 }{ 2 } /- \frac{ 5 }{ 6 } )$$

Answer

-5

Solution


Move the negative sign to the left.
\[-\frac{\frac{1}{4}}{-\frac{3}{2\times -5\times 6}}\]
Simplify  \(2\times -5\)  to  \(-10\).
\[-\frac{\frac{1}{4}}{-\frac{3}{-10\times 6}}\]
Simplify  \(-10\times 6\)  to  \(-60\).
\[-\frac{\frac{1}{4}}{-\frac{3}{-60}}\]
Move the negative sign to the left.
\[-\frac{\frac{1}{4}}{-(-\frac{3}{60})}\]
Simplify  \(\frac{3}{60}\)  to  \(\frac{1}{20}\).
\[-\frac{\frac{1}{4}}{-(-\frac{1}{20})}\]
Remove parentheses.
\[-\frac{\frac{1}{4}}{\frac{1}{20}}\]
Invert and multiply.
\[-\frac{1}{4}\times 20\]
Simplify  \(\frac{1}{4}\times 20\)  to  \(\frac{20}{4}\).
\[-\frac{20}{4}\]
Simplify  \(\frac{20}{4}\)  to  \(5\).
\[-5\]
