Answer 1

To determine if the two statements \( \frac{2.5}{10} = \frac{12}{48} \) and \( \frac{2.52}{1224} \) form proportions, we analyze each.

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

   • Simplifying \( \frac{12}{48} \): \[ \frac{12}{48} = \frac{1}{4} \]
   • Simplifying \( \frac{2.5}{10} \): \[ \frac{2.5}{10} = \frac{25}{100} = \frac{1}{4} \]
   • Since \( \frac{2.5}{10} = \frac{12}{48} = \frac{1}{4} \), these fractions are equal.

2. For \( \frac{2.52}{1224} \):

   • We can calculate this: \[ 2.52 = \frac{252}{100} \]
   • Now we can compare \( \frac{252}{100} \) and \( \frac{1224}{1} \):
     • Cross multiplying: \[ 252 \times 1 = 252 \quad \text{and} \quad 100 \times 1224 = 122400 \]
     • Since \( 252 \neq 122400 \), \( \frac{2.52}{1224} \) is not equal.

Putting this all together:

• The first statement \( \frac{2.5}{10} = \frac{12}{48} \) is a valid proportion.
• The second statement \( \frac{2.52}{1224} \) is not a valid proportion.

Thus, the conclusion is: Both are proportions. This response is incorrect. The correct response is Neither is a proportion.
