What is the first step in the indirect proof?

A) If you have 12 dogs and cats (I assume 12 in total) and divide those by two, you get six dogs and six cats. It has to be more dogs than cats, and the sum of those two has to be twelve. So to reach the sum 12, while one number is bigger that the other, the number has to be 7 or more.

To add any fraction You need to make sure that the denominator of the fractions are same. ( denominator in your sum is 19 )

10/19 + 3/19 ( we have the same denominator )
we can also write this problem like
( 10 + 3 ) / 19 { add the numerators together }
13 / 19

So correct option is B.

hope this helped.. :)
