Neither is a proportion.
wrong
Both of the given pairs are proportions. The correct answer is:
16/8 = 24/12 AND 8/4 = 12/6.
how did you get that answer
To determine if something is a proportion, we need to test if the ratios are equal.
For 16/8 = 24/12, we simplify both sides to get 2 = 2, which means they are equal. This is a proportion.
For 8/4 = 12/6, we simplify both sides to get 2 = 2, which means they are equal. This is also a proportion.
Therefore, both pairs are proportions.

2 point 5 over 2 is equal to 12 over 24 - no response given
Both are proportions.
Both are proportions. - no response given
2.510=1248
2.510 = 12/48
2.52 = 12/24
In the case of 2.510 = 12/48, the ratio of 12 to 48 can be simplified to 1/4, not equal to 2.510. Therefore, this is not a proportion.
In the case of 2.52 = 12/24, the ratio of 12 to 24 is equivalent to 1/2, which is equal to 2.52. Therefore, this is a proportion.
Therefore, the answer is: 2.52 = 12/24 is a proportion.

2.5/010 = 12/48
2.5/2 = 12/24
In the case of 2.5/010 = 12/48, simplifying the left hand side gives us 0.25 = 0.25, which is equal to the right hand side. Therefore, this is a proportion.
In the case of 2.5/2 = 12/24, simplifying both sides gives us 1.25 = 0.5, which is not equal. Therefore, this is not a proportion.
Therefore, the answer is: 2.5/010 = 12/48 is a proportion.
