  • 1, 25cm=1250mm^3
    1 menit=60 detik
    =1250×60=90000

    0,4 liter/m^3=400000cm^3
    1 jam=60 menit
    =400000×60=24000000

    0, 25dm^3=25000cm^3
    1 jam=3600 detik
    25000×3600=90000000

    1, 25=125 cl
    1jam=60 menit
    125×60=7500

    250cl=2, 5 l
    1jqm=3600 detik
    3600×2, 5=90000

    0, 05 liter=5000cm^3
    1 jam=3600 detik
    5000×3600=1800000

    0,0002 dm^3=0, 2liter
    1jam=3600 detik
    3600×0, 2=19200

    maaf ya kalo salahnya banyak soal
    Semoga bisa membantu
    bila ada salah, maaf
  • 1) 25 cm³/dtk
    = 25 × 1.000 / 1/60
    = 25 × 1.000 × 60/1
    = 1.500.000 mm³/mnt

    2) 0,4 liter/mnt
    = 0,4 × 1.000 / 1/60
    = 0,4 × 1.000 × 60/1
    = 24.000 cm³/jam

    3) 0,25 dm³/dtk
    = 0,25 × 1.000 / 1/3600
    = 0,25 × 1.000 × 3.600/1
    = 900.000 cm³/jam

    4) 1,25 liter/jam
    = 1,25 × 100/ 60
    = 2,08 cl/mnt

    5) 250 cl/dtk
    = 250 × (1/100 ÷ 1/3600)
    = 250 × 3600/100
    = 9.000 liter/jam

    6) 0,05 liter/dtk
    = 0,05 × 1000 / 1/3600
    = 0,05 × 1.000 × 3600/1
    = 180.000 cm³/jam

    7) 0,0002 dm³/jam
    = 0,0002 × 1 / 3600
    = 0,06 × 10^-6
    = 6 × 10^-8 liter/dtk
