  1. a, 300+50+0,06
    =350+0,06
    =350,06
    b, 50+0,6+0,07
    = 50 + (0,6+0,07)
    =50+0,67
    =50,67
    c, 200+6+3/100
    =200+6+0,03
    =206+0,03
    =206,03

  2. a ) 300 + 50 + 0,06 = 350 + 0,06 = 350,06
    b ) 50 + 0,6 + 0,007 = 50,6 + 0,07 = 50,67
    c ) 200 + 6 + 3/100 = 206 + 0,03 = 206,03
