1000gram harganya 75000
300gram harganya x

1000/75000 = 300/x
1/75 = 300/x
x = 75.300
x = 22500

1 kg = 1000 gr

1kg       = 75.000

1000gr  = 75.000
300 gr   = x (perumpamaan)

1000/300 = 75.000/x
1000 x    = 75.000 x 300
1000 x    = 22.500.000
       x     = 22.500.000
                    1000
       x    = 22.500
