No.

Dividing by a fraction is equivalent to multiplying by its reciprocal.

To simplify the complex fraction 5/8 ÷ 5, you can follow these steps:

1. Divide the numerator of the fraction (5) by the reciprocal of the denominator (8). The reciprocal of 8 is 1/8.
So, 5 ÷ (1/8) = 5 x 8/1 = 40/1 = 40.

Therefore, the simplified form of the complex fraction 5/8 ÷ 5 is 40.

Based on your given calculation, it looks like you multiplied the numerator and denominator instead of dividing them. So, your calculation of 5/8 divided by 5 as 25/8 is not correct.

The correct steps to divide 5/8 by 5 would be:
1. Take the reciprocal of the number you are dividing by. In this case, the reciprocal of 5 is 1/5.
2. Multiply the fraction 5/8 by the reciprocal 1/5.
5/8 x 1/5 = (5 x 1) / (8 x 5) = 5/40 = 1/8.

Hence, the correct simplified form of the complex fraction 5/8 ÷ 5 is 1/8, not 25/8.
