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?
2/5 j = 3/4 k or k = 8/15 j
k already has LESS money than j giving him any amount of money will not make them equal
You're absolutely right!!!
In order for them to have the same amount of money, Josh MUST give $28 to Ken!!!
But, in the following equation, Ken will "give" $28 to Josh!?!? It's weird!!!
2/5x + 28 = 3/4x - 28
x = 160
Josh had $120 3/4(160) = 120 120 - 28 = 92 2/5(120) = 48
Ken had $64 2/5(160) = 64 64 + 28 = 92 3/4(64) = 48
