Can anyone help me out with this badboy?

Find a method for converting a repeating expansion (with any periodt and any numbers of non-repeating digits between the point and the rst repeating digit) from binary tohexadecimal, without converting to base ten at any stage. Then convert the repeating binaryexpansion10101.001101 (the last 5 digits 01101 are repeating)to hexadecimal (without using base ten). [Note the one non-repeating digit before the re-peating part.]
