Answer 1

Answer:

~ 50 centimeters of 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:

     5         =           1      ⇒   x - centimeters of the poster

     x                     10

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

5 * 10 = x,

x = 50 centimeters of the poster
