Answer:
~ 1.25 centimeters of the snowflake in real life ~
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:
12 = 1 ⇒ x - centimeters of the snowflake in real life
15 x
2. Now let us cross multiply, and solve through simple algebra for x:
15 = 12 * x
x = 1.25 centimeters of the snowflake in real life
