1. **State the problem:** Solve the inequality \(\left|\frac{1}{2}w - \frac{3}{4}\right| < 2\).
2. **Recall the rule for absolute value inequalities:**
If \(|A| < b\), then \(-b < A < b\).
3. **Apply the rule:**
\[-2 < \frac{1}{2}w - \frac{3}{4} < 2\]
4. **Add \(\frac{3}{4}\) to all parts to isolate the term with \(w\):**
\[-2 + \frac{3}{4} < \frac{1}{2}w < 2 + \frac{3}{4}\]
Convert \(-2\) and \(2\) to quarters:
\[-\frac{8}{4} + \frac{3}{4} < \frac{1}{2}w < \frac{8}{4} + \frac{3}{4}\]
Simplify:
\[-\frac{5}{4} < \frac{1}{2}w < \frac{11}{4}\]
5. **Multiply all parts by 2 to solve for \(w\):**
$$2 \times \left(-\frac{5}{4}\right) < 2 \times \frac{1}{2}w < 2 \times \frac{11}{4}$$
Intermediate step showing cancellation:
$$\cancel{2} \times \left(-\frac{5}{4}\right) < \cancel{2} \times \frac{1}{2}w < \cancel{2} \times \frac{11}{4}$$
Simplify:
$$-\frac{10}{4} < w < \frac{22}{4}$$
Simplify fractions:
$$-\frac{5}{2} < w < \frac{11}{2}$$
6. **Final answer:**
\[-\frac{5}{2} < w < \frac{11}{2}\]
7. **Interval notation:**
\(\left(-\frac{5}{2}, \frac{11}{2}\right)\)
8. **Decimal form:**
\(-2.5 < w < 5.5\)
