Question

Determine if 2.510=?1248 or 2.52=?1224 is a proportion.(1 point) Responses Neither is a proportion. Neither is a proportion. Both are proportions. Both are proportions. 2.52=1224 Start Fraction 2.5 over 2 End Fraction equals Start Fraction 12 over 24 End Fraction 2.510=1248

Answer 1

To determine if the given expressions form proportions, we can rearrange them as fractions and check if they are equal.

For the first expression, "2.510 = ?1248":
- Assuming ?1248 represents a value to be identified (likely a zero), we can interpret this as:
\[ \frac{2.5}{10} = \frac{12}{48} \]

Calculating the fractions:
- \( \frac{2.5}{10} = 0.25 \)
- \( \frac{12}{48} = 0.25 \)

Since both sides equal 0.25, the first expression is a proportion.

Now for the second expression, "2.52 = ?1224":
- Similarly, we interpret it as:
\[ \frac{2.52}{2} = \frac{12}{24} \]

Calculating the fractions:
- \( \frac{2.52}{2} = 1.26 \)
- \( \frac{12}{24} = 0.5 \)

Since \( 1.26 \) does not equal \( 0.5 \), the second expression is not a proportion.

In conclusion:
- "2.510 = ?1248" is a proportion.
- "2.52 = ?1224" is not a proportion.

So, the response is: **Neither is a proportion.**
