Step-by-step explanation:

-2/3 * 3/5 + 5/2 - 3/5 * 1/6

= 2/3 * 3/5 - 3/5 * 1/6 + 5/2

[ Using associative property ]

= 3/5 * (-2/3 - 1/6 ) + 5/2

[ Using distributive property ]

= 3/5 * {( -4 - 1 ) /6} + 5/2

( LCM ( 3, 2 ) = 6 ]

= 3/5 * (-5 / 6 ) + 5/2

= 3/6 + 5/2

= 1/2 + 5/2

= (-1 / 5)/2

= 4/2

= 2
