247-410 sao chia được

5781 : [ 928 - ( 247 - 82 . 5 )

5781 : [ 928 - 164,5 ]

5781 : 763,5 =7,571709234

5871⁰ : [928 - (247 - 82).5] + 2175⁰

= 1 : (928 - 165.5) + 1

= 1 : (928 - 825) + 1

= 1 : (-103) + 1

= 102/103

\(=5871:\left[928-165\cdot5\right]\\ =5871:\left[928-825\right]=5871:103=57\)

\(=5871:\left[928-165.5\right]=5871:\left[928-825\right]=5871:103=57\)
