13%. When doing problems with linear reactions, convert the percents into decimals, then multiplying the decimals. So the calculation would be 0.98*0.45*0.66*0.87*0.50 = 0.13 = 13%. Remember to keep significant figures, since we were given only 2 significant figures at most, we keep only 2 in the final answer.
