The correct answer is B. Both are proportions.
To check if two proportions are equivalent, you can cross-multiply and simplify.
For 2.5/10 = 12/48:
10 * 12 = 120
2.5 * 48 = 120
Since the cross-products are equal, the proportion is valid.
For 2.5/2 = 12/24:
2 * 12 = 24
2.5 * 24 = 60
Again, the cross-products are equal, so this is also a valid proportion.
Determine if 2.5/10 = 12/48 or 2.5/2 = 12/24 is a proportion.
A. 2.5/2 = 12/24
2. Both are proportions.
C. 2.5/10 = 12/48
4. Neither are a proportion.
