Question

A chess player played 20 games total. If he won 2 of the games, what is the ratio of games he lost to games he won?

Answer 1

So, we have useful information to answer this question. We know that he played 20 games and he won 2 games. To find the ratio of the games lost, we have to subtract the number of games played and the number of games won. 
20-2=18
So now we can find the ratio of games won and games lost
The answer is 18:2, 18 to 2, or 18/2.
You can also simplify the ratio to 9:1
So the final answer is 9:1

Hope this helped
