Starting fraction, n%2Fd.

The changed fraction, %28%281%2F2%29n%29%2F%28%283%2F4%29d%29. You may need to think about the expression carefully for it to make sense...

Simplify the changed fraction.
%28%281%2F2%29%2F%283%2F4%29%29%28n%2Fd%29
'
%284%2F%282%2A3%29%29%28n%2Fd%29
'
%282%2F3%29%28n%2Fd%29

Returning back to percents, the common fraction is {something not renderable}, or 66%262%2F3%, repeating digits of 6 as 66.66666666..... %.
