On the blueprints of their new home, Paul and gertha notice the balcony is 9 inches long and 4 inches wide they know that the actual balcony will be 15.3 ft long. How wide will the balcony be?

We can solve this with a proportion

 

width on blueprint  /  length on blueprint   =  x / actual length

 

4/9  = x / 15.3     cross-multiply

 

15.3 *4  =  9x     simplify

 

61.2  = 9x       divide both sides by  9

 

6.8 in = the width
