Final answer:
The correct number that is a solution to the inequality g < 7.2 is Option A: 5. That's because it is the only option provided that is less than 7.2, satisfying the inequality condition.
Step-by-step explanation:
The question is asking us to find which number is a solution to the inequality g < 7.2. To solve this, we examine each provided option to determine if it is less than 7.2.
- Option A: 5 is less than 7.2, so it satisfies the inequality g < 7.2.
- Option B: 7.2 is not less than 7.2, so it does not satisfy the inequality.
- Option C: 8 is greater than 7.2, so it does not satisfy the inequality.
- Option D: 9.6 is much greater than 7.2, so it does not satisfy the inequality.
Therefore, the correct answer is Option A: 5, since it is the only number among the options that is less than 7.2.
