Bab Perbandingan
Matematika SMP Kelas VII

pria = p
wanita = w

260.000 p + 210.000 w = 250.000 (p + w)
260.000 p + 210.000 w = 250.000 p + 250.000 w
260.000 p - 250.000 p = 250.000 w - 210.000 w
10.000 p = 40.000 w
p : w = 40.000 : 10.000
p : w = 4 : 1

jawabannya E

pria = x
wanita = y

(260000x + 210000y)/(x + y) = 250000

26x + 21y = 25x + 25y
26x-25x = 25y-21y
x = 4y

x/y = 4/1

perbandingannya 4 : 1
