The average score of Wang Hua's three math exams is 102 (the full score of each exam is 120).
Let the fourth score be at least x and establish the equation:

120 is greater than or equal to (3* 102+2x)/5 is greater than or equal to 108.

120 ≥ (306+2x)/5 ≥ 108

120 is greater than or equal to 6 1.20+2x/5 is greater than or equal to 108.

120 ≥ 2x/5 ≥ 46.8

If the solution is 120, x is greater than or equal to 1 17, that is, at least 1 17 points will be scored for the fourth time.

Is this detailed enough?
