⟹( \frac{3}{5}  \times  \frac{5}{6}) - ( \frac{9}{11}  \times  \frac{4}{3} ) + ( \frac{5}{13}  \times  \frac{6}{15} )

⟹( \frac{1}{11}  \times  \frac{5}{2} )  - ( \frac{3}{11}  \times 4) + ( \frac{1}{13}  \times  \frac{6}{3} )

⟹( \frac{5}{22} ) - ( \frac{12}{11}) +  \frac{2}{13}

⟹ \frac{5 - 24}{22}  +  \frac{2}{13}

⟹  - \frac{19}{22}  +  \frac{2}{13}

l.c.m \: of \: 22 \: and \: 13 = 286

⟹ \frac{ - 19 \times 13 + 2 \times 22}{286}  =  \frac{ - 247 + 44}{286}

⟹ -  \frac{203}{286}

Answer:

Step-by-step explanation:

Consider, (3/11 × 5/6) − (9/12 × 4/3) + (5/13 × 6/15)

= (1/11 × 5/2) − (1/1 × 1/1) + (1/13 × 2/1) {Cancelling the terms]

= (5/22) − 1 + (2/13)

= [65 − 286 + 44] / 286

= [109 − 286] / 286

= −[177] / 286
