for every 4 lost games , games won = 9
for every 1 lost game , games won = 9/4
for every 28 games lost , games won = 9/4 * 28
= 252/4
=63 games
what we did is that we first divided 9 by 4 to find the number of games won for every 1 game lost
Now once we get number of games won for every 1 game lost
we can simply multiply it by 28 to get the number of games won , for 28 lost games.
So answer is 63 games
