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

180 millimeters.

Explanation:

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

`(x)/(50)= (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.
