4/6=408/X CROSS MULTIPLY
4X=408*6
4X=2448
X=2448/4
X=612 FEET TALL FOR THE CHIMNEY
-------------------------------------------------------------
90/X=.75/1.5
.75X=90*1.5
.75X=135
X=135/.75
X=180 METERS TALL
------------------------------------------------------------
4FT 5 1/2 IN/X=3/6
3X=6*53.5
3X=321
X=321/3
X=107 INCHES
------------------------------------------------------------
14/X=9FT4IN/4
112X=14*12*4
112X=672
X=672/112
X=6 FT. TALL FOR THE MAN.
