Penjelasan dengan langkah-langkah:
PERBANDİNGAN
1. 12 tahun : 5 windu
= 12 : ( 5 × 8 )
= 12/4 : 40/4
= 3 : 10
2. 30 menit : 6 jam
= 30/30 : (6 × 60/30)
= 1 : 12
3. Jarak sebenarnya = 30 × 40.000/100.000
= 1.200.000/100.000
= 12 km
4. 12 × 125 = p × 100
1.500 = 100p
p = 1.500/100
p = 15 orang pekerja
5. 20 × 30 = (20 – 5) × h
600 = 15h
h = 600/15
h = 40 hari
