Answer :
The answers would be 3/4, 8/12, and 10/15.
Since 7/8 is greater than 3/4, its always true so infinite solutions
Simplify 8/12 to 2/3 and since 7/8 is greater than 2/3 its correct
Simplify 10/15 to 2/3 and since 7/8 is greater than 2/3 its true so infinite solutions.
Since 7/8 is NOT greater than 9/10 its false so no solutions.
Since 7/8 is greater than 3/4, its always true so infinite solutions
Simplify 8/12 to 2/3 and since 7/8 is greater than 2/3 its correct
Simplify 10/15 to 2/3 and since 7/8 is greater than 2/3 its true so infinite solutions.
Since 7/8 is NOT greater than 9/10 its false so no solutions.
