<PRE><B>Question 811881</B>
The question is a bit hazy. Is the father just working half his time which means  mowing half the lawn? 
If they both work the same amount of time then 
x/4+x/6=1
x=12/5 =2.4 hours which means that he did .6 and she did .4

if he only mows half the lawn
means they both do half  the lawn
x/6=1/2
x=3
