Let x=width of house on scale drawing

Since "1/8 inch represents 1 foot " and "The foundation of a house is 30 feet wide", this means that we have the equation %281%2F8%29%2F1=x%2F30 which simplifies to 1%2F8=x%2F30


1%2F8=x%2F30 Start with the given ratio


%281%2F8%29%2A30=x Multiply both sides by 30


30%2F8=x Multiply


15%2F4=x Simplify



So our answer is x=15%2F4 which in decimal form is x=3.75


So the width of the house on the scale drawing is 3.75 inches.
