Mostly convert the binaries into decimals, thats formats you are familiar with. It will take time... So attempt last.

6) 260
binary equivalent=10000100
so jus replace 1 with $ and 0 with *

7)60/17 is also equivalent to 180/51
coz $$**$$==110011===== binary equivalent of 51 which is 17*3
hence 60*3=180
therefore 60/17 is also = 180/17
===10110100/110011
===$*$$*$**/$$**$$
hence option C is correct

8)$***$
===10001 which is ===17
option B is $*$*$-$$
===10101-11
===20-3====17
hence option B is correct
