Final answer:
Sarah has 33 green buttons if she has 22 red buttons, based on a ratio of 3 to 2.
Step-by-step explanation:
To find the number of green buttons Sarah has, we can set up a proportion using the given ratio.
The ratio is 3 to 2, meaning for every 3 green buttons, there are 2 red buttons.
We are given that Sarah has 22 red buttons.
So, we can set up the proportion:
3/2 = x/22.
Cross multiplying, we get 2x = 3 * 22.
Solving for x, we find that Sarah has 33 green buttons.
