Question

5 * 20,09 + 4 * 20,09 - 2009 * 28,18 + 2009 * 20,09

Answer 1

5*20.09+4*20.09-2009*28.18+2009*20.09

= ( 5+4)*20.09-2009*(28.18+20.19)

=9*20.09-2009*48.37

=180.81-97175.33
=0
 

Answer 2

5 * 20,09 + 4 * 20,09 - 2009 * 28,18 + 2009 * 20,09

= 20,09 * ( 5 + 4) - 2009 * ( 20,18 - 20,09)

= 20,09 * 9 - 2009 * 0,09

= 20,09 * 9 - 20,09 * 100 * 0,09

= 20,09 * 9 - 20,09 * 9 = 0

Answer 3

5.20,09+4.20,09-2009.28,18+2009.20,09

=20,29.(5+4)-2009.(20,18+20,19)

=20,09.9-2009.48,37

=20,09.9-20,09.100.0,09

=20,09.(9-100.0,09)

=20,09.0=0
