2/5 of Josh's money was 3/4 of Ken's money. When Ken gave Josh $28, both of them would have the same amount of money. How much did Josh have at first?
We can write an equation where j= josh's money and k = ken's money.
This is impossible...to see why
(2/5)J = (3/4)K
J = (5/2)(3/4)K
J = (15/8)K
So...originally....Josh has more money than Ken - (15/8) ths as much
So...if Ken gives Josh $28......they can't possibly have the same amount......
