Neither is a proportion.

Answer 1

To determine whether \( \frac{2.5}{10} = \frac{12}{48} \) and \( \frac{2.52}{2} = \frac{12}{24} \) are proportions, we need to compare the fractions.

1. For \( \frac{2.5}{10} \) and \( \frac{12}{48} \):

   • Calculate \( \frac{2.5}{10} = 0.25 \).
   • Calculate \( \frac{12}{48} = 0.25 \).
   • Since both sides are equal, \( \frac{2.5}{10} = \frac{12}{48} \) is indeed a proportion.

2. For \( \frac{2.52}{2} \) and \( \frac{12}{24} \):

   • Calculate \( \frac{2.52}{2} = 1.26 \).
   • Calculate \( \frac{12}{24} = 0.5 \).
   • Since \( 1.26 \neq 0.5 \), \( \frac{2.52}{2} \neq \frac{12}{24} \) is not a proportion.

So, the correct response is:

• \( \frac{2.5}{10} = \frac{12}{48} \) is a proportion.
• \( \frac{2.52}{2} = \frac{12}{24} \) is not a proportion.

Thus, the answer is: Neither is a proportion.
