Stephanie drew a picture of her house with her prize rosebush in the front. In her picture, she drew the rosebush 1.5 centimeters tall, and she drew the house 7.5 centimeters tall. If her rosebush is really 0.75 meter tall and she made her drawing to scale, what scale did she use?

1 cm= 75cm

1 cm =5cm
