![## Solving Proportions: Practice Problems
Below are a set of proportion problems. Each equation involves a ratio that is set equal to another ratio. Your task is to solve for the unknown variable in each proportion.
1. **Problem 5:**
\[
\frac{24}{13} = \frac{x}{39}
\]
Find the value of \(x\).
2. **Problem 6:**
\[
\frac{10}{30} = \frac{50}{y}
\]
Solve for \(y\).
3. **Problem 7:**
\[
\frac{3.6}{4.3} = \frac{k}{21.5}
\]
Determine the value of \(k\).
4. **Problem 8:**
\[
\frac{9}{11} = \frac{13.5}{b}
\]
Calculate the value of \(b\).
### Instructions:
To solve each proportion, use cross-multiplication to find the unknown variable. For example, if the proportion is:
\[ \frac{a}{b} = \frac{c}{d} \]
you would solve it by calculating \(ad = bc\).](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F3167c75e-aacf-4280-86b9-3831059afe2f%2F61f627b1-1dc1-4b00-a434-6c68c9940f35%2Fh72bcn_processed.png&w=3840&q=75)
