Let's break down the information given:
-
Five-ninths of the bracelet is white. This means that the proportion of the bracelet that is white is \( \frac{5}{9} \).
-
The remaining part of the bracelet is red and gray. Since the total of the bracelet is 1 (or \( \frac{9}{9} \)), the remaining portion can be calculated as:
\[ 1 - \frac{5}{9} = \frac{4}{9} \]
- This remaining \( \frac{4}{9} \) is composed of equal amounts of red and gray beads. Therefore, we divide this by 2 to get the proportion of red beads and the proportion of gray beads:
\[ \frac{4}{9} \div 2 = \frac{4}{9} \times \frac{1}{2} = \frac{4}{18} = \frac{2}{9} \]
Thus, the amount of gray beads in Charlotte's bracelet is \( \frac{2}{9} \).
So, the answer is:
\(\frac{2}{9}\)
