Answer 1

Answer:

~ 84 cm of the pop in the poster ~

Step-by-step explanation:

Let us plan out our steps, and solve for each:

1. Given the information, let us create a proportionality as such:

      7          =              1      ⇒   x - centimeters of the pop in the poster

      x                         12

2. Now let us cross multiply, and solve through simple algebra for x:

7 * 12 = x,

x = 84 centimeters of the pop in the poster
