makasih banyak ;) jawabanmu sangat membantu ☺
= x 1 kg
= 0,7 kg
berat 15 liter bensin = 15 x 0,7
= 10,5 kg
5a) 48 gram emas 18 karat
emas murni = x 48 gram
= 36 gram
logam lain = x 48 gram
= x 48 gram
= 12 gram
b) 120 gram emas 22 karat
emas murni = x 120 gram
= 110 gram
logam lain = x 120 gram
= x 120 gram
= 10 gram
c) 180 gram emas 23 karat
emas murni = x 180 gram
= 23 x 7,5 gram
= 172,5 gram
logam lain = x 180 gram
= x 180 gram
= 7,5 gram
