The ratio 9:7 gives you following statement:
- Carl will win in 9 cases from 9+7=16;
- Carl will lose in 7 cases from 16.
Then the probability that Carl will lose is

Answer: 
You can obtain the a number for which they all divisors by calculating the least common multiple.
This way:
85 = 5*17*1
17=17*1
19=19*1
4=2^2 *1
2=2*1
The least common multiple is: 5*17*19*2^2 = 6,460.
Then 84, 17, 19, 4 and 2 are all divisors of 6,460.
You should search it up on Photomath is easier
there is 1 number 3 on a 6 sided die
so the probability or rolling a 3 is 1/6
So what you need to start with is taking the x from both sides as adding 12 to them. Then, you move the 27 over 4 decimals.
