The reciprocal of 4/11 is 11/4.
This is because the reciprocal of a fraction is 1 divided by the original fraction, for example: 1/(4/11) = 11/4. A simple shortcut that we can use, though, is just simply switching the numerator and the denominator to find the reciprocal, because this will give you the same answer as 1 divided by the original fraction.
Hope this helps!
