Question

(16⅔% × 3 ton) - (33⅓% × 1½ kuintal) =. ..........kg. (pakai cara)

Answer 1

Jawab:

(16⅔% × 3 ton) - (33⅓% × 1½ kuintal) =. ..........kg

Diketahui:
1 ton = 1000 kg
1 kwintal = 100 kg

Maka: caranya kita ubah dulu bentuk diatas sebagai berikut:

16 2/3% =( 3 x 16+2)/3
= 50/3%
= 50/3/100/1
= 50/3 x 1/100
= 50/300
= 5/30
= 1/6

3 ton = 3 x 1000 kg
= 3000 kg

33 1/3% = (3x33+1)/3%
= 100/3%
= 100/3/100/1
= 100/3 x 1/100
= 100/300
= 1/3
1 1/2 kwintal
= (2x1+1)/2 kwintal
= 3/2 kwintal
= 3/2 x 100 kg
= 3 x 100/2 kg
= 300/2 kg
= 150 kg

Sehingga:

(16⅔% × 3 ton) - (33⅓% × 1½ kuintal)
= ( 1/6 x 3000 kg)-(1/3 x 150kg)
=( 1 x 3000kg/6)-( 1 x 150 kg/3)
= (3000kg/6)-(150kg/3)
= 500 kg - 50 kg
= 450 kg
