- 5/12 x 72/21 - 3 /4 ( 2 + 2/21 )

= - 360/252 - 3 /4 ( 42/21 + 2/21 )

= - 360 /252 - 3 /4 * 44/21

= - 360/252 - 132/84

=  - 10 /7 - 11/7

= - 21 /7

= - 3

( 5/2 - 1/4 ) x 5/6 - ( 3 - 7 /6 )

=  ( 10/4 - 1/4) x 5 /6 - ( 18/6 - 7 /6 )

= 9/4  x 5 /6 - 11/6

= 45/24 - 11/6

= 45/24 - 44 /24

= 1/24
