To write 260400 as a percent, you interpret it as a fraction of 100.
To convert a number to a percentage, you would usually divide the number by the total from which you want to find the percentage. However, without specifying a total, it's unclear how you want to assess 260400 as a percent.
If you assume the total is 1, the percentage would be:
\( 260400 \times 100 = 26040000 % \)
But, since the options provided do not match this interpretation, it seems you may need to find it as a percentage of a lesser value or context.
If you're looking for a percent representation of a value relative to a total not given in your context, more information would help clarify this.
Given the potential context of the numbers provided (which may not include 260400), none of the options you have presented seem to fit.
Can you clarify or provide a context to better match one of the options?
