20,15 x 96 + 20,15 : 0,25

 

Answer 1

20,15x96+20,15:0,25=20,15x96+20,15x4

                                =20,15x(96+4)

                                   =20,15x100

                             =2015

Answer 2

= 20,15 x 96 + 20,15 x 4

= 20,15 x ( 96 + 4)

= 20,15 x 100

= 2015

Answer 3

20,15 x 96 + 20,15 : 0,25

= 20,15 x 96 + 20,15 x 4

= 20,15 x ( 96 + 4 )

= 20,15 x 100

= 2015

Answer 4

\(20,15\times96+20,15\div0,25\)

     \(=20,15\times96+20,15\times4\)

     \(=20,15\times\left(96+4\right)\)

      \(=20,15\times100\)

      \(=2015\)

Answer 5

20,15×96+20,15:0,25 =20,15×96+20,15×4 =20,15×(96+4) =20,15×100 =2015
