Hey mate, Here is your desired answer :)

Answer:

-17 / 168

Step-by-step explanation:

= [ (2/11 ) × (-22/15 ) ] + [ (-1/6 ) × (-3/4 ) ] + [ (-1/21 ) × (-3/5 ) ]

=(-4/15) + (1/8) + (1/35)

=L.C.M. of 15, 8, 35 is 840.

=[ (-4×56 )/840 ] + [ (1×105 )/840 ] + [ (1×24 )/840 ]

=(-224/840) + (105/840) + (24/840)

=(-224 + 105 + 24 ) / 840

=-85 / 840

=-17/168
