A rectangular picture window 12-feet long and 6-feet wide needs to be shortened to 9 feet in length to fit in a redesigned wall. If the architect wants the new window to be similar to the old window, how wide will the new window be?
To find the desired width we need to solve the equation: [tex]\frac{9}{12}=\frac{x}{6}[/tex] [tex]\frac{3}{4}=\frac{x}{6}[/tex] [tex]x=\frac{3*6}{4}=\frac{18}{4}=\frac{9}{2}=4.5[/tex]
