Answer 3

a,= ( 25x4 ) x ( 13x5 )

   = 100 x 65

    = 6500

     = ( 125x8 ) x ( 87x4 )

      = 1000 x 348

       = 348000

b,    = ( 50x2 ) x 76

        = 100 x 76

        = 7600

         = ( 4x25 ) x ( 19x8 )

          =100 x 152

           = 15200

          c, = ( 20x5 ) x ( 303x6 )

               = 100 x 1818

                = 181800

               = ( 4x25 ) x 889

               = 100 x 889

                = 88900

Answer 4

a, 25 x 5 x 13 x 4 = 6500

    87 x 125 x 8 x 4 = 348000

b, 50 x 76 x 2 =7600

    19 x 4 x 25 x 8 = 15200
