Question

Tolong kaa Deng caranya piss

Answer 1

Verified answer

1. 1 jam = 60 menit

Jadi:
1,5 jam
= 3/2 × 60
= 90 menit

2. 1km = 10 hm

Jadi:
30 km
= 30 × 10
= 300 hm

3. 1 lusin = 12 buah

Jadi:
1/2 lusin
= 1/2 × 12
= 6 buah

1 buah = 1/20 lusin

Jadi:
6 buah
= 6 ÷ 20
= 3/10 kodi

4. 1 kg = 1000 gram

Jadi:
1/4 kg
= 1/4 × 1000
= 250 gram

5. 3/4 ÷ 1/5
= 3/4 × 5/1
= 15/4
= 3 3/4

Answer 2

1) 1,5 jam : 60 menit
= 1,5 × 60 menit : 60 menit
= 90 menit : 60 menit = 90 :60 = 9 : 6 = 3 : 2

2) 30 km : 12 hm
= 300 hm : 12 hm
= 300 : 12 = 25 : 1

3) 1,5 lusin : 2/5 kodi
= 1,5 × 12 buah : 2/5 × 20 buah
= 18 buah : 8 buah
= 18 : 8 = 9 : 4

4) 1/4 kg : 20 gram 
= 0,25 kg : 20 gram = 250 gram : 20 gram
= 250 : 20 = 25 : 2

5) 3/4 : 1/5
= × : ×
= :
= 15 : 4
