  1. a)
    y : 42 = 16 + 17,38
    y : 42 = 33,38
    y = 33,38 xx 42
    y = 1401,96 
    Vậy y = 1401,96
    b)
    y : 17,03 = 60
    y = 60 xx 17,03
    y  = 1021,8
    Vậy y=1021,8
     

  2. a, y : 42 = 16 + 17,38
    y : 42 = 33,38
    y = 33,38 xx 42
    y = 1401,96
    b, y : 17,03= 60
    y = 60 xx 17,03
    y = 1021,8
