An artist draws a picture of a house with a rose bush in front. In his picture the rose bush is 1.5cm high and the house is 7.5cm high. In reality the rose bush is .75 metres high. How tall is the house (in metres)?
x = artist's scale
Convert meters to centimeters
In reality, rose bush = .75m * 100 cm/m = 750 cm
Solve for x
1.5x = 750
x = 750/1.5
x = 500 cm
IF artist's scale = 1 cm:500cm THEN
house = 7.5cm * 500 cm
= 3750 cm
= 3.75 m

Yeah that is right.
