The problem in the image asks how many exams Kiana studied for, given that:

- She studied for a total of \( 2 \frac{1}{4} \) hours.
- She spent \( \frac{3}{4} \) hour studying for each exam.

We can solve this by dividing the total time Kiana studied by the time she spent on each exam.

### Step 1: Convert Mixed Number to Improper Fraction
First, convert \( 2 \frac{1}{4} \) hours into an improper fraction:

\[
2 \frac{1}{4} = \frac{9}{4}
\]

### Step 2: Divide by \( \frac{3}{4} \)
Now, divide \( \frac{9}{4} \) by \( \frac{3}{4} \):

\[
\frac{9}{4} \div \frac{3}{4} = \frac{9}{4} \times \frac{4}{3} = \frac{9 \times 4}{4 \times 3} = \frac{36}{12} = 3
\]

### Conclusion:
Kiana studied for 3 exams.

Thus, the correct answer is **D) 3**.

Here are some related questions for practice:
1. How would the result change if Kiana spent 1 hour per exam instead of \( \frac{3}{4} \) hours?
2. If Kiana had studied for 5 hours, how many exams could she have prepared for at the same rate?
3. How do you convert between mixed numbers and improper fractions?
4. What if Kiana had studied for \( 3 \frac{1}{4} \) hours? How many exams would that be?
5. Can you think of another situation where you’d need to divide fractions in real life?

**Tip:** When dividing fractions, always remember to multiply by the reciprocal of the divisor.
