tara
joe
lynn
they pool their money

If I put the 2/3 in the numerator of the
last term, my common denominator is y

divide through by y

One way to check this is to plug in numbers
let x = 6
let y = 3
x has to be bigger than y so joe doesn't lose money
and y can't be 0. division by 0 not allowed
tara = 2
joe = 1
lynn = 4/3
add them up
2 + 1 + 4/3 = 13/3
now use

checks OK
