You could add up all the relative frequencies to make sure that you have 100% accounted for.
The relative frequency is the percent out of 100% for a particular item. If you have found the relative frequency for all items, it should equal 100%.
I'm not sure what exactly the question is asking for, but the value if this expression should be 56.
Add what are in the parentheses, 29+18=47 and 17-8=9.
Then add up those values, 47+9=56.
