To express the number 125 in percent form, you can convert it by multiplying by 100.
So, \( 125 \times 100 = 12500% \).
However, it seems like the options you've provided do not include the correct conversion for 125 itself.
If you're looking at 0.125, that would be 12.5% or if you're looking at a ratio like 0.125 out of a total of 1, it might lead to the perception of 12.5%, but for the number 125 itself, the correct answer is 12500%.
If you meant to write or find a different ratio or number referring to 125, please clarify!
