Question 1011052
William fills 1/3 of a water bottle in 5/9 of a
minute. How many bottles can he fill in a
minute? 
Please explain this to me so I can explain it to my grandaughter 
who is in 7th grade, but special education student.

Not sure if your grandaughter can handle a proportion,
but that is the way to solve it.
----
Proportion:: # of bottles/time = # of bottles/time
----------
# of bottles/(1 min) = (1/3 bottle)/(5/9 min)
-----
Divide by "1" on the left side.
Divide by (5/9) on the right side.
------
Ans: # of bottles = (1/3)/(5/9) = (1/3)(9/5) = 9/15 = 3/5 of a bottle

Thanks for helping your grandaughter.
Cheers,
