Determine if 2.510=?1248 or 2.52=?1224 is a proportion.
To determine if an equation is a proportion, we need to check if the ratios of the corresponding terms on both sides are equal.
In the equation 2.510 = ?1248, the corresponding terms are 2.5 and 1248. So, the ratio is 2.5/1248.
In the equation 2.52 = ?1224, the corresponding terms are 2.52 and 1224. So, the ratio is 2.52/1224.
To check if these ratios are equal, we can cross-multiply:
(2.5)(1224) = 3114
(2.52)(1248) = 3145.76
Since 3114 is not equal to 3145.76, the two equations are not proportions.
To determine if 2.510 = ?1248 or 2.52 = ?1224 is a proportion, we need to find the ratio of the two numbers on each side of the equal sign and see if they are equal.
For 2.510 = ?1248:
The ratio is 2.510 / ?1248.
To find the missing value (?), we can cross multiply:
2.510 * ? = 2.510 * 1248
? = (2.510 * 1248) / 2.510
? = 3129.12
So, 2.510 = 3129.12 is not a proportion.
For 2.52 = ?1224:
The ratio is 2.52 / ?1224.
To find the missing value (?), we can cross multiply:
2.52 * ? = 2.52 * 1224
? = (2.52 * 1224) / 2.52
? = 1224
So, 2.52 = 1224 is a proportion.
