6000 : 3 = 2000
harga 7 pensil = 2000 x 7 = 14000

tapi klo pakek perbandingan senilai caranya kayak gini =
3 pensil = 6000
7 pensil = X
3/7 = 6000/X = X * 3 = 6000 * 7 : 3 = 14000
kalo pakek pecahan senilai caranya kayak gitu ya

3 batang pensil = Rp 6.000
Berarti 1 batang pensil = 6000/3 = 2000

7batang pensil = 7 x 2000 = Rp 14.000
