An architect builds a scale model of a building, where 1 cm = 0.5 m. If the scale model is 15 cm tall, how tall will the actual building be, in meters, written as a decimal?

The actual building will be 7.5 m tall

Step-by-step explanation:

Given the scale model value of the building, we want to find the actual height of the building

From the scale model;

1 cm = 0.5m

Thus 15 cm will be 15 * 0.5 = 7.5 m
