To express \(0.942\) as a fraction using equations, here’s a step-by-step solution based on the information in the image.

### Solution Steps:

1. **Set up an equation**:
   Let \( x = 0.942 \).

2. **Shift the decimal point to create similar terms**:
   Multiply both sides by \( 10 \), \( 100 \), and \( 1000 \) sequentially to shift the decimal point:
   - \( 10x = 9.42 \)
   - \( 100x = 94.2 \)
   - \( 1000x = 942.42 \)

3. **Form an equation to eliminate the repeating decimal**:
   Subtract the equation with \(10x\) from the equation with \(1000x\) to eliminate the decimal part.
   \[
   1000x - 10x = 942.42 - 9.42
   \]
   Simplifying, we get:
   \[
   990x = 933
   \]

4. **Solve for \( x \)**:
   Divide both sides by \(990\):
   \[
   x = \frac{933}{990}
   \]

5. **Simplify the fraction**:
   To simplify \(\frac{933}{990}\), we find the greatest common divisor (GCD) of \(933\) and \(990\), which is \(3\):
   \[
   x = \frac{933 \div 3}{990 \div 3} = \frac{311}{330}
   \]

Thus, \(0.942\) as a fraction is \(\frac{311}{330}\).
