      0.9     12
     ————— = ————
      1.5      n

Multiply both sides by 1.5n


      0.9          12
1.5n·————— = 1.5n·————
      1.5           n

Cancel:

      0.9       1  12
1.5n·————— = 1.5n·————
      1.5           n
       1            1
       

      0.9n = 1.5(12)

      0.9n = 18

Divide both sides by 0.9

      0.9n      18
     —————— = —————
       0.9     0.9

Cancel on left.

      0.9n      18
     —————— = —————
       0.9     0.9
        1

Divide on right


          n = 20
