2 ) 2,1 ton = 2,1 × 1000 kg = 2100 kg
4. 1/4 kuintal = 17/4 × 100 kg = 425 kg
4. 1/5 kuintal = 21/5 × 100 kg = 420 kg

Jumlah berat seluruhnya
= 2100 kg + 425 kg + 420 kg
= 2.945 kg

3 ) Ayah
= 2/5 × 1.500 m2
= 600 m2

Paman
= 3/10 × 1.500 m2
= 450 m2

Sisa tanah kakek
= 1.500 m2 - ( 600 m2 + 450 m2 )
= 1.500 m2 - 1.050 m2
= 450 m2
