Convert 26/100 to decimal and solve F+8=0 and F/8=0.

Dividing by 100 means moving the decimal point two places to the left.

$$26 \div 100 = 0.26$$

The student's work for this part is correct.
The decimal form is $\boxed{0.26}$.

$$F + 8 = 0$$ $$F + 8 - 8 = 0 - 8$$

$$F = -8$$

The solution for the first equation is $\boxed{F = -8}$.

$$F = 0$$

The solution for the second equation is $\boxed{F = 0}$.
