To determine the remaining ratio of orange beads in the friendship bracelets, we first need to understand the total ratios of the beads:
- The ratio of blue beads is given as \( \frac{3}{10} \).
- The ratio of yellow beads is given as \( \frac{1}{10} \).
Adding these two ratios gives us the total proportion of blue and yellow beads:
\[ \frac{3}{10} + \frac{1}{10} = \frac{4}{10} \]
Now, this fraction can be simplified to:
\[ \frac{4}{10} = \frac{2}{5} \]
Next, the total ratio of all beads must equal 1 (or \( \frac{10}{10} \)). Thus, the remaining ratio for orange beads can be found by subtracting the combined ratio of blue and yellow from 1:
\[ 1 - \frac{2}{5} = \frac{5}{5} - \frac{2}{5} = \frac{3}{5} \]
So, the remaining ratio of orange beads in each bracelet is \( \frac{3}{5} \).
Final Answer: \( \frac{3}{5} \)
