Question

Ada beras sebanya 16 2/3 kg, akan dikemas dalam 1/3kg sebanyak 17 bungkus dan 1/4kg sebanyak 26 bungkus . sisanya akan dikemas dalam kemasan 1/2kg . ada berapa bungkus banyak kemasan 1/2kg tersebut ?

Answer 1

16 2/3 = (17 x 1/3) + (26 x 1/4) + (n x 1/2)
n x 1/2 = 50/3 - 17/3 - 26/4
n x 1/2 = (200-68-78)/12
n x 1/2 = 54/12
n = 54/12 x 2
n = 9

Answer 2

Total beras = 16 ⅔ kg = 50/3 kg
1/3 kg × 17 = 17/3 kg
1/4 kg × 26 = 26/4 kg = 13/2 kg
misal yg d bungkus 1/2 kg = x
maka : total = 17/3 kg + 13/2 kg + x
50/3 = 17/3 + 13/2 + x
x = 50/3 - 17/3 - 13/2
x = 100/6 - 34/6 - 39/6
x = 27/6
x = 9/2
x = 9 × ½ artinya ada 9 bgkus kmsan ½ kg
