Question

\(-\dfrac{\text{11}}{\text{24}}:\dfrac{\text{17}}{\text{23}}-\dfrac{\text{11}}{\text{24}}:\dfrac{\text{17}}{\text{11}}-\dfrac{1}{\text{12}}\)

Answer 1

- \(\dfrac{11}{24}\) : \(\dfrac{17}{23}\) - \(\dfrac{11}{24}\) : \(\dfrac{17}{11}\) - \(\dfrac{1}{12}\)

= - \(\dfrac{11}{24}\) x \(\dfrac{23}{17}\) - \(\dfrac{11}{24}\) x \(\)\(\dfrac{11}{17}\) - \(\dfrac{1}{12}\)

= - \(\dfrac{11}{24}\) x (\(\dfrac{23}{17}\) + \(\dfrac{11}{17}\)) - \(\dfrac{1}{12}\)

= - \(\dfrac{11}{24}\) x 2 - \(\dfrac{1}{12}\)

= - \(\dfrac{11}{12}\) - \(\dfrac{1}{12}\)

=- \(\dfrac{12}{12}\)

= - 1
