Ordering Proportions in Descending Order

To arrange the given proportions in descending order, we convert each fraction into its decimal form to facilitate comparison.

• A. $\frac{3}{13} \approx 0.2308$
• B. $\frac{4}{17} \approx 0.2353$
• C. $\frac{5}{19} \approx 0.2632$
• D. $\frac{7}{15} \approx 0.4667$
• E. $\frac{2}{5} = 0.4000$

Comparing Decimal Values

Now, we arrange these decimal values from largest to smallest:

1. $0.4667$ (D)
2. $0.4000$ (E)
3. $0.2632$ (C)
4. $0.2353$ (B)
5. $0.2308$ (A)

Final Descending Order

Therefore, the proportions in descending order are D, E, C, B, A.

This corresponds to Option 1.
