Question 880578: If M,K,L can do a work in 4, 6 , and 8 hours; if they work simultaneously then what fraction of work is done by the M? Answer by josmiceli(19441) (Show Source):
You can put this solution on YOUR website! M does ( 1 job ) / ( 4 hrs )
K does ( 1 job ) / ( 6 hrs )
L does ( 1 job ) / ( 8 hrs )
-----------------------------
Add their rates of working to
get their rate working together
Multiply both sides by
---------------------
Together, they take hr
to do 1 job
For K:
For L:
M does 6/13 of the work
check:
OK
