Ted's best friend, Ben, finds him a way to deal with it. If he borrows one from Ben, it will make the cows twenty. Then he can first give half of the twenty cows to Rex. Next, Ann and Rob can get one-fourth and one-fifth of the twenty ones. Ten plus five and four equals nineteen. Ted therefore can give back the borrowed cow and solve the problem. Ben’s idea is good, isn’t it?
