Question 130029: Can someone help? I am stuck on 2 word problems.
Melanie can paint a certain barn by herself in X days. Her helper Melissa can paint the same barn by herself in 2X days. Write a rational expression for the fraction of the barn that they complete in one day by working together. Evaluate the expression for X=5.
Thanks I am lost..

If Melanie can paint the barn in x days, then she can paint of the barn in one day.
If Melssa can paint the barn in 2x days, then she can paint of the barn in one day.
So, together, they can paint of the barn in one day.

Working together, Malanie and Melissa can paint of the barn in one day.
If x = 5, then = of the barn.
