Alejandro's error lies in the incorrect conversion from a fraction to a percent. The correct method involves dividing the numerator (5) by the denominator (8) to get a decimal, and then multiplying by 100 to convert it to a percent.
The correct steps would be:
- Calculate \( \frac{5}{8} = 0.625 \).
- Convert 0.625 to a percent by multiplying by 100: \( 0.625 \times 100 = 62.5% \).
In Alejandro's steps, he incorrectly divided 8.0 by 5, which is not the correct operation for converting the fraction to a decimal.
Therefore, the answer that best explains Alejandro’s error is:
The division was completed in the incorrect order.
