The photo and poster of known dimensions are similar figures at a ratio of 4.
What is a proportion?
A proportion is a value that allows us to know variable values of a set of elements that are related by means of a constant.
If we want to know if these two figures are similar or proportional, they must be at a ratio, (both dimensions), for this we formulate the following:
This will generate an equation:
2x = 8
3x = 8
When solving for both values of "x" it must be exactly the same:
- x = 8/2 = 4
- x = 12/3 = 4, The picture and poster are similar.
