please help me with these circuits:
a JK flipflop using a D flip flop and a multiplexer
a 5 to 32 decoder using four 3 to 8 decoders and a 2 to 4 decoder,
thanks, a picture would help more

How are going to learn anything if we just hand you the answer?

Analyze the problem (what inputs and outputs do you need) and tell us what your questions are on generating those circuits.

Yes, it's important that we see you are attempting to solve the problem.

For example, look at the characteristics of a D FF as compared to a JK FF and determine what signals you need to convert one to the other.

P.S. Why did you post here? This should be in the homework section.

Hi,
This should give you a little guidance for the JK.
