  1. a) 1240 cm = 124 dm
    1 dm = 10 cm
    b) 3425 cm = 34 m 25 cm
    1 m = 100 cm
    c) 1642 cm = 16 m 42 cm
    10 m = 1000 cm
    d) 12 dm^2 9mm^2 = 1200,09 cm^2
    1 dm^2 = 100 cm^2
    e) 360 mm = 36 cm
    1 cm = 10 mm
    g) 328 cm = 3 m 28 cm
    1m = 100 cm
    h) 2874 kg = 2 tấn 874 kg
    1 tấn = 1000 kg
    i) 27m^2 32cm^2 = 2700,32 dm^2 
    1 m^2 = 100 dm^2
     

  2. $a,1240 cm = 124 dm$
    $b, 3425 cm = 34 m 25 cm$
    $c, 1642 kg =16 tạ  42 kg$
    $d, 12 dm² 9 mm²=1200,09 cm²$
    $e, 360 mm= 36 cm$
    $g, 328 cm =3 m 28 cm$
    $h, 2874 kg = 2 tấn 874 kg$
    $i, 27 m² 32 cm² = 2700,32 dm$
