# a building casts a shadow 48 feet long. at the same time, a 40-foot-tall flagpole casts a shadow 9.6 feet long . what is the height of the building

$\frac{40}{9.6} = \frac{48}{n}$ Reduce the fraction on the left by dividing by 8  (remember 8 goes into 96 so it will go into 9.6 too) $\frac{5}{1.2} = \frac{48}{n}$  Now cross multiply. 5n = 57.6   finally divide both sides by 5 n= 11.52 ft - answer
