Answer 1

6) 1548 → 18
n → 6
perbandingan senilai, didapat :
1548/n = 18/6
1548/n = 3
3 x n = 1548
n = 1548 : 3
n = 516 ....(D)

Answer 2

8) uang = x
orang = n

x/n = 63 000 >> x=63 000n

x/n+1 = 52 500 >> x=52 500n + 52 500


63 000n = 52 500n + 52 500
63 000n - 52 500n = 52 500
10 500n = 52 500
n = 52 500/10 500
n = 5


x/n = 63 000
x/5 = 63 000
x = 63 000×5
x = 315 000
