thank you

You're welcome.

To simplify a ratio, you need to divide both the numerator and the denominator by their greatest common divisor (GCD). The GCD is the largest number that evenly divides both numbers.

Here's a step-by-step guide to simplify a ratio:

1. Write down the given ratio in the form of "a:b" or "a to b."
2. Calculate the GCD of the numerator (a) and the denominator (b).
3. Divide both the numerator (a) and the denominator (b) by their GCD.
4. Write down the simplified ratio.

Let's illustrate this with an example:

Example: Simplify the ratio 12:18.

1. The given ratio is 12:18.
2. Find the GCD of 12 and 18. The factors of 12 are 1, 2, 3, 4, 6, and 12. The factors of 18 are 1, 2, 3, 6, 9, and 18. The largest number that divides both 12 and 18 evenly is 6. So, GCD = 6.
3. Divide both the numerator (12) and the denominator (18) by 6: 12 ÷ 6 = 2 and 18 ÷ 6 = 3.
4. The simplified ratio is 2:3.

So, the simplified ratio of 12:18 is 2:3.
