To determine if 2.510=?1248 or 2.52=?1224 is a proportion, we need to cross-multiply and check if the resulting equations are equal.
For the first equation 2.510=?1248:
2.510 * 1248 = 3133.248
2.510 * 1 = 2.510
As 3133.248 is not equal to 2.510, the first equation is not a proportion.
For the second equation 2.52=?1224:
2.52 * 1224 = 3080.48
2.52 * 1 = 2.52
As 3080.48 is not equal to 2.52, the second equation is also not a proportion.
Neither of the equations are proportions.
To determine if 2.510 = ?1248 or 2.52 = ?1224 is a proportion, we need to check if the two ratios are equal.
Let's set up the first proportion:
2.510 / x = ?1248 / 1
To find the value of x, we can cross-multiply:
2.510 * 1 = ?1248 * x
2.510 = ?1248 * x
Dividing both sides of the equation by ?1248 will give us:
2.510 / ?1248 = x
Now, let's set up the second proportion:
2.52 / y = ?1224 / 1
Cross-multiplying:
2.52 * 1 = ?1224 * y
2.52 = ?1224 * y
Dividing both sides by ?1224:
2.52 / ?1224 = y
Comparing the two values we found, x and y, can help determine if the given expressions are a proportion.
