To determine if either of the pairs is a proportion, we need to check if the ratios are equal.
A proportion states that two ratios are equal:
\(\frac{a}{b} = \frac{c}{d}\).
1. **For \(2.510 = 1248\)**:
- This can be rewritten as:
\(\frac{2.5}{10} = \frac{12}{48}\).
Now, simplify both fractions:
- \(\frac{2.5}{10} = \frac{1}{4}\).
- \(\frac{12}{48} = \frac{1}{4}\).
Since both simplified values are equal, \(2.510 = 1248\) is a proportion.
2. **For \(2.52 = 1224\)**:
- This can be rewritten as:
\(\frac{2.5}{2} = \frac{12}{24}\).
Now, simplify both fractions:
- \(\frac{2.5}{2} = \frac{5}{4}\).
- \(\frac{12}{24} = \frac{1}{2}\).
Since \(\frac{5}{4} \neq \frac{1}{2}\), \(2.52 = 1224\) is not a proportion.
**Conclusion**: Only the first case (\(2.510 = 1248\)) is a proportion. Therefore, the correct response is:
**2.510 = 1248 is a proportion.**
