Question

The Arc de Triomphe measures 50 m in height. You are asked to make a replica model in art class using a scale of 1:275. What should the height of your model be in millimeters?

Answer 1

Answer:

180 millimeters.

Step-by-step explanation:

To find the height of the replica, a ratio can be set up:

$\frac{x}{50}= \frac{1}{275}$

Cross multiply:

$275x = 50$

Divide both sides by '275:

x≈0.18 meters

Convert 'meters' to 'millimeters' by multiplying by a thousand:

0.18 × 1000 = 180 millimeters.
