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:

  1. Calculate \( \frac{5}{8} = 0.625 \).
  2. 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.
