dimastoro Diketahui 3/4 kodi = 15 buah

15 buah = 2250 000
maka harga 8 buah dan 1 buah

$\frac{15}{8} = \frac{2250000}{n}$

$n = \frac{2250000*8}{15}$ = 1200000

1 buah
$\frac{15}{1} = \frac{2250000}{n}$

$n = \frac{2250000*1}{15}$ = 150000

YanuarRama Nih kan hari 3/4 kodi kain sarung 2.250.000 maka kalo mencari harga 8 buah kain sarung harus dikali silang. misalkan kain sarung itu adalah α
mencari harga 8 buah kain 2.250.000/α = 15/8 = α = 2.250.000 × 8 ÷ 12 = 1.200.000
mencari harga 1 buah kain sarung tinggal dibagi 8 aja = 1.200.000 ÷ 8 = 150.000
