Question

Write a proportion for the following problem. Eric is making a scale drawing of the ground floor of his house. If the scale is 2 inches = 5 feet, what number of inches will he use for a length of 55 feet?

Answer 1

Actually, a more proper way to do that is to convert 5 feet into inches-> 60 inches. Now convert 55 into inches-> 660. Now, the units are same.
\[\LARGE 2:60::x:660 \]

Answer 2

2/5 = 55/x


2/55 = x/5

2/5 = x/55

Answer 6

Let me solve it.
\[\LARGE {2 \over 60} = {x \over 660}\]
\[\LARGE {2(660)} = 60x \]
\[\LARGE {1320} = 60x \]
\[\LARGE x = {1320 \over 60} \]
\[\LARGE x = 22 \]
\[\LARGE \text{Answer is 22 inches.} \]
