To determine if the equation is a proportion, we need to check if the ratios on both sides of the equation are equal.
Comparing 2.510 and 1248, we have the ratio 2.510/1248 which is approximately equal to 0.002 (rounded to three decimal places).
Comparing 2.52 and 1224, we have the ratio 2.52/1224 which is approximately equal to 0.002 (rounded to three decimal places).
Since the ratios on both sides of the equation are equal, 2.510/1248 = 2.52/1224, we can conclude that the equation is a proportion.

Both are proportions.
To determine if the equation is a proportion, we need to check if the ratios on both sides of the equation are equal.
Comparing 2.5/10 and 12/48, we have the ratio (2.5/10)/(12/48). Simplifying this, we get (2.5/10) * (48/12) = 12/10 which is equal to 1.2.
Comparing 2.5/2 and 12/24, we have the ratio (2.5/2)/(12/24). Simplifying this, we get (2.5/2) * (24/12) = 5/2 which is equal to 2.5.
Since the ratios on both sides of the equation are not equal (1.2 ≠ 2.5), we can conclude that neither equation is a proportion.
Comparing 2.5/10 and 12/48, we have the ratio (2.5/10)/(12/48). Simplifying this, we get (2.5/10) * (48/12) = 12/10 which is equal to 1.2.
Comparing 2.5/2 and 12/24, we have the ratio (2.5/2)/(12/24). Simplifying this, we get (2.5/2) * (24/12) = 5/2 which is equal to 2.5.
Since the ratios on both sides of the equation are not equal (1.2 ≠ 2.5), we can conclude that neither equation is a proportion.

To determine if the equations are proportions, we need to check if the ratios on both sides of each equation are equal.
For the first equation, 16/8 = 24/12, we have the ratio (16/8)/(24/12). Simplifying this, we get (16/8) * (12/24) = 2 * 0.5 = 1. The ratio on both sides is equal to 1, so the first equation is a proportion.
For the second equation, 8/4 = 12/6, we have the ratio (8/4)/(12/6). Simplifying this, we get (8/4) * (6/12) = 2 * 0.5 = 1. The ratio on both sides is equal to 1, so the second equation is also a proportion.
Therefore, both equations are proportions.
For the first equation, 16/8 = 24/12, we have the ratio (16/8)/(24/12). Simplifying this, we get (16/8) * (12/24) = 2 * 0.5 = 1. The ratio on both sides is equal to 1, so the first equation is a proportion.
For the second equation, 8/4 = 12/6, we have the ratio (8/4)/(12/6). Simplifying this, we get (8/4) * (6/12) = 2 * 0.5 = 1. The ratio on both sides is equal to 1, so the second equation is also a proportion.
Therefore, both equations are proportions.

The correct proportion that shows how much 5 gallons of gas will cost is:
15/45 = x/5
This can be read as "15 is to 45 as x is to 5".
15/45 = x/5
This can be read as "15 is to 45 as x is to 5".
