If the ratio of milk chocolate to dark chocolate in a Valentine's Day candy box is 2 to 3, and there are 8 milk chocolates, we can find the number of dark chocolates by setting up a proportion.
We know that the ratio of milk chocolate to dark chocolate is 2 to 3. So, we can set up the following proportion:
2/3 = 8/x
To solve for x, we can cross multiply:
2x = 3 * 8
2x = 24
Dividing both sides of the equation by 2, we get:
x = 12
Therefore, there are 12 dark chocolates in the Valentine's Day candy box.
