Kelas 6 Matematika
Bab Pengukuran

1 raket + 6 kok = 700 kg
350 gram + 6 kok = 700 kg 
6 kok = 700 x 1.000 gram - 350 gram
1 kok = (699.650 gram) / 6
1 kok = 116.608,33 gram
1 kok = 116,60833 kg

6 kok + raket = 700 kg
raket = 350 g

6 kok = 700 kg - 350 g
6 kok = 700.000 - 350
6 kok = 699.650

1 kok = 699.650/6
1 kok = 116.608,33 gram
