To determine if the two statements are proportions, we need to analyze each one.
-
First statement: \(2.510 = ?1248\)
This can be interpreted as: \[ \frac{2.5}{10} = \frac{12}{48} \]
Now, let's simplify both fractions:
- For \( \frac{2.5}{10} \): \[ \frac{2.5}{10} = \frac{25}{100} = \frac{1}{4} \]
- For \( \frac{12}{48} \): \[ \frac{12}{48} = \frac{1}{4} \]
Since both fractions simplify to \( \frac{1}{4} \), this statement is a proportion.
-
Second statement: \(2.52 = ?1224\)
This can be interpreted as: \[ \frac{2.5}{2} = \frac{12}{24} \]
Now, let's simplify both fractions:
- For \( \frac{2.5}{2} \): \[ \frac{2.5}{2} = \frac{25}{20} = \frac{5}{4} \]
- For \( \frac{12}{24} \): \[ \frac{12}{24} = \frac{1}{2} \]
Since \( \frac{5}{4} \) does not equal \( \frac{1}{2} \), this statement is not a proportion.
Conclusion:
The final classification:
- First statement \( \frac{2.5}{10} = \frac{12}{48} \) is a proportion.
- Second statement \( \frac{2.5}{2} = \frac{12}{24} \) is not a proportion.
Thus, the correct answer is: 2.510 = 1248 is a proportion; 2.52 = 1224 is not a proportion.
