Tolong jawab ya... guru nya galak nih....

Kotak 3 dan 4 itu tidak ada isinya jadi kita ubah :v

Kotak 1 = Bruto = 50 kg
Neto = 49 kg
Tara = 50-49 = 1 kg

Persentase Neto = 49/50 x 100 = 98%
Persentase Tara = 1/50 x 100 = 2%

Kotak 2 = Bruto = 25 kg
Tara = 0,5 kg
Neto = 25 - 0,5 = 24,5 kg

Persentase Neto= 24,5/25 x 100 = 98%
Persentase Tara = 0,5/25 x 100 = 2%

Kotak 3 = Ubah dulu :v
Neto 1,85 = 18,5
Tara 150 = 1,50

Neto = 18,5 kg
Tara = 1,50 kg
Bruto = 18,5 + 1,50 = 20 kg

Persentase Neto = 18,5/20 x 100 =92,5%
Persentase Tara = 1,50/20 x 100 = 7,5%

Kotak 4 = ubah dulu :)
Tara 120 = 1,20

Bruto = 6 kg
Tara = 1,20 kg
Neto = 6 - 1,20 = 4,8 kg

Persentase Neto = 4,8/6 x 100 = 80%
Persentase Tara = 1,20/6 x 100 = 20%

Semoga membantu :)
