$ a) 486,3 × 1,75 + 486,3 × 9,15 - 486,3 - 10,89 $
$ = 486,3 × ( 1,75 + 9,15 - 10,89 ) = 486,3 × 0,01 = 4,863 $
$ b) 20,12 × 80 + 40,24 × 2 + 201,2 $
$ = 20,12 × 80 + 20,12 × 8 + 20,12 × 10 = 20,12 × ( 80 + 8 + 10 ) = 20,12 × 98 = 1971,76 $
$ c) 3,65 : 0,125 + 3,65 : 0,25 - 7,3 $
$ = 3,65 × 8 + 3,65 × 4 - 3,65 × 2 = 3,65 × ( 8 + 4 - 2 ) = 3,65 × 10 = 36,5 $ 
$ d) 17,6 : 0,125 + 17,6 : 0,25 - 35,2 $
$ = 17,6 × 8 + 17,6 × 4 - 17,6 × 2 = 17,6 × ( 8 + 4 - 2 ) = 17,6 × 10 = 176 $
