Question

On a blueprint the Length of a wall is 5 cm is the actual length of the wall is 15 feet what is the scale of the blueprint

Answer 1

Make a ratio comparing the two values; you can use either 5:15 or 15:5

A ratio, as always can be written as a fraction, like this:
5/15 or 15/5

Simplify the fraction:
1/3 or 3

Convert back into ratio:
1:3 or 3


Depending on the type of ratio you need, you can use either one.

Hope this helps!
