Algebra.Com's Answer #735650 by Shin123(626)![]() ![]() You can put this solution on YOUR website! Ana can complete 1/5 of the job in a hour and Beth can complete x of the job in a hour. 1 divided by 1/5+x should be 3. So 1/5+x=1/3 .2+x=0.33333... x=0.133333333... x=2/15=1/7.5 Beth can complete 1/7.5 of the job in a hour. So the answer is D.
