no 1 ya pakek cara please

1 liter = 1 dm3
1 dm3 = 0,001 m3

Jadi 2500 liter = 2500 dm3 = 2,5 m3

1. 1 liter = 1 dm^3
2.500 dm^3 ÷ 1.000 = 2,5 m^3 (B)

2. 1 are = 100 m^2
4,75 m^2 ÷ 100 = 0,0475 are (A)

3. 1 are = 100 m^2
345 are × 100 = 34.500 m^2 ÷ 100= 345 dam
78 m^2 ÷ 100 = 0,78 dam

345 dam^2 + 0,78 dam^2 = 345,78 dam^2(B)

4. 1 liter = 1 dm^3 1 menit = 60 detik
36 dm^3/menit × 1.000 = 36.000 cm^3 ÷ 60 detik = 600 cm^3/detik

5. 1 jam = 60 menit
40 ÷ 60 menit = 2/3 jam
2 2/3 jam

SEMOGA MEMBANTU :)
