Question 31391: tara made x/y dollars for babysitting.joe made x-y/y and lynn made 2/3 as much as tara.if they all pool their money.how much will they have? Answer by josmiceli(19441) (Show Source):
You can put this solution on YOUR website! 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
