Answer:

~ <em>50 centimeters of the poster ~</em>

Step-by-step explanation:

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

<em>1. Given the information, let us create a proportionality as such:</em>

<em />

     5         =           1      ⇒   x - centimeters of the poster

     x                     10

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

5 * 10 = x,

x =<em> 50 centimeters of the poster </em>

<em></em>
