Answer:
18 : 30
Explanation:
Our ratio could look like this:
Number of games won : Number of games played
6 : 10
=> .6 : 1
Let's check whether the 1st option is correct.
=> 18 : 20
=> 1 x 20 = 20
=> .6 x 20 = 12
=> 12 : 20 is not equal to 18 : 20
The second option is 100% incorrect because the number of games won is greater than the number of games played.
let's check whether the 3rd option is correct.
=> 18 : 30
=> 1 x 30 = 30
=> .6 x 30 = 18
18 : 30 = 18: 30
So, the 3rd option is correct.
