Bab PerbandinganMatematika SD Kelas VI
Gito = a
Gita = b
a : b = 3 : 4
a = 3b/4
a + 25.000 = b - 25.000
3b/4 + 25.000 = b - 25.000
3b + 100.000 = 4 (b - 25.000)
3b + 100.000 = 4b - 100.000
4b - 3b = 100.000 + 100.000
b = 200.000
a = 3b/4
a = 3 x 200.000 / 4
a = 600.000/4
a = 150.000
jadi, uang Gito = Rp 150.000,00
uang Gita = Rp 200.000,00
Verified answer
Uang Gito = xUang Gita = y
x : y = 3 : 4
x = 3y/4
y - 25000 = x + 25000
y - 25000 - 25000 = 3y/4
y - 3/4 y = 50000
1/4 y = 50000
y = 4 × 50000
y = uang Gita = 200000
x = 3/4 y
x = 3/4 × 200000
x = uang Gito = 150000
Jadi, uang mreka masing-masing :
Uang Gito = 150000
Uang Gita = 200000
