+128598 Notice that 1/6.5 = 2/13 and this is the part of the field that Marcos can paint in one hour
And Carlos paints 1/4 of the field every hour.
So....here's an easy way to solve these kind of problems.....
Add the two fractions = 1/4 + 2/13 = [13 + 8] / 52 = 21/52
Now....invert the fraction = 52/21 = about 2.48 hours......and that's how long it takes both to finish the job working together....!!!!
