Step 1   We convert each fraction into percentages as  23=(23×100)%  =2003%  =66.67%  12=(12×100)%  =1002%  =50%  710=(710×100)%  =70010%  =70%  Step 2   Now we can arrange these percentages into descending order as   75%, 70%, 66.67%, 62.5%, 50%.   Replacing the percentages with fractions results  75%,710,23,62.5%,12.  So option (b) is the correct answer.
