Explanation:
Given,
\left(\frac{3}{11}\times\frac{5}{6}\right)-\left(\frac{9}{12}\times \frac{4}{3}\right)+\left(\frac{5}{13}\times \frac{6}{15}\right)(

=\left(\frac{5}{22}\right )-\left(\frac{36}{36}\right)+\left(\frac{2}{13}\right)(

)−(

)
=\left(\frac{5}{22}\right )-1+\left(\frac{2}{13}\right)(

)−1+(

)
=\frac{5\times 13-286+2\times 22}{286}
286
5×13−286+2×22
=\frac{65-286+44}{286}
286
65−286+44
=\frac{109-286}{286}
286
109−286
= \frac{-177}{286}
