Jawaban:

• Nomor 1:

3 kodi : 1 gros

Jawab =

3 kodi = 20 x 3 = 60

1 gros = 144

Jadi = 204 lembar

• Nomor 2:

2 km : 300 m

Jawab =

2 km = 1000 m x 2 = 2000 m

Jadi = 2000 : 300 = 6,66 m/0,00666 km

• Nomor 3:

4 kg : 500 g

4 kg = 1000 g x 4 = 4000 g

Jadi = 4000 : 500 = 8 g/0,008 kg

• Nomor 4

180 menit : 2 jam

180 menit = 3 jam

Jadi = 3 : 2 = 1,5 jam/90 menit
