Question

A blueprint for a house uses a scale of 1.4 cm.:6.5 ft. The actual house is 52 ft. tall. How tall is the house in the blueprint?

241.2 ft
11.2 cm
11.2 ft
241.4 cm

Answer 1

The house in the blueprint is 11.2 cm tall, because when you cross multiply you get 6.5x = 72.8 and when you divide 72.8 by 6.5, you get 11.2

$\frac{1.4}{6.5} = \frac{x}{52}$
