a) 356 : 4 + 44 : 4

 =( 44 + 356 ) : 4

 = 400 : 4

 = 100

b) 5525 : 5 + 2125 : 5 -2650 : 5

  = ( 5525 + 2125 - 2650 ) : 5

  = 5000 : 5

  = 1000

 c) 522 : 3 + 222 : 3

  = ( 522 + 222) : 3

  = 744 : 3

  = 248

 d) 3192 : 7 - 2170 : 7

   = ( 3192 - 2170 ) : 7 

   = 1022 : 7

   = 146

a, 27x75 + 25 x 27 - 25 x 6

=27 x ( 75 + 25 ) - ( 25 x 6 )

= 27 x 100 - ( 25 x 6 )

= 2700 - ( 25 x 6 )

= 2700 -  150

= 2550
