Prime numbers are really important when it comes to simplifying ratios. They help us find the greatest common divisor (GCD).

Key Points:

1. What are Prime Numbers?

   • Prime numbers are whole numbers greater than 1.
   • They can only be divided evenly by 1 and themselves.
   • Some examples are: 2, 3, 5, 7, and 11.

2. How to Find the GCD:

   • The GCD is super useful when we want to simplify a ratio.
   • For example, let’s look at the ratio 12:8. We can break down both numbers:
     • 12 can be factored into (2^2 \times 3) (which is 4 times 3)
     • 8 can be factored into (2^3) (which is 2 times 2 times 2)
   • The GCD here is 4.

3. Simplifying the Ratio:

   • Now, we take the ratio parts and divide both by the GCD:
     • (\frac{12}{4}) gives us 3
     • (\frac{8}{4}) gives us 2
   • So, the simplified ratio is 3:2.

In conclusion, prime numbers help us find the GCD, making it easier to simplify ratios to their simplest form!
