To determine if two fractions are a proportion, you need to check if they are equivalent.
Let's simplify both fractions:
For 2.5/10=12/48:
The numerator and denominator of 2.5/10 can be divided by 2:
2.5/10 = 1.25/5
The numerator and denominator of 12/48 can be divided by 12:
12/48 = 1/4
Therefore, 1.25/5 is not equal to 1/4.
For 2.5/2=12/24:
The numerator and denominator of 2.5/2 can be divided by 2.5:
2.5/2 = 1/0.8
The numerator and denominator of 12/24 can be divided by 12:
12/24 = 1/2
Therefore, 1/0.8 is not equal to 1/2.
Since neither 2.5/10=12/48 nor 2.5/2=12/24 are equivalent fractions, neither of them is a proportion.
Determine if 2.5/10=12/48 or 2.5/2=12/24 is a proportion. (1 point)
