The length of the Titanic was 882 feet. Porter's history class is building a model of the Titanic. The model is 1/100 of the actual length of the ship. How long is the model?

1 Answer

8.82 feet

Explanation:

Let's set up the ratio. We know that the actual length of the ship was 882 feet and we want to know how long the model will be. We also have a ratio of 1 model length to every 100 actual length. So we can write this as:

#"Model length"/"Ship length"="1 Model length"/"100 actual length"#

And we can drop in some numbers (I'll also put in the variable #x# to represent the length of the ship model):

#x/882=1/100#

Let's cross multiply to solve for x:

#100x=882#

#x=8.82# feet
