A tile is the basic unit that makes an entire floor pattern what fraction is white? Green? Yellow? brown?

To determine the fraction of each color in a floor pattern, you need to know the number of tiles of each color and the total number of tiles in the pattern. Without that information, I'm unable to provide you with the exact fraction for each color.

However, I can guide you through the steps to calculate it if you have the required data. Here's what you can do:

1. Count the number of white tiles in the floor pattern.
2. Count the number of green tiles in the floor pattern.
3. Count the number of yellow tiles in the floor pattern.
4. Count the number of brown tiles in the floor pattern.
5. Add up the counts from steps 1 to 4 to determine the total number of tiles.
6. Once you have the total number of tiles, divide the count of each color tile by the total, separately, to find the fraction of each color.

For example, let's say you counted 20 white tiles, 15 green tiles, 10 yellow tiles, and 5 brown tiles. If the total number of tiles is 50, you can calculate the fractions as follows:

- Fraction of white tiles = (Number of white tiles) / (Total number of tiles) = 20 / 50 = 2/5
- Fraction of green tiles = (Number of green tiles) / (Total number of tiles) = 15 / 50 = 3/10
- Fraction of yellow tiles = (Number of yellow tiles) / (Total number of tiles) = 10 / 50 = 1/5
- Fraction of brown tiles = (Number of brown tiles) / (Total number of tiles) = 5 / 50 = 1/10

Remember, these calculations depend on the actual count of each color tile and the total number of tiles present in the floor pattern.
