Find how many squares are currently shaded, then determine how many need to be shaded to reach 75% of the total.<br><br>
• Count the total number of squares in the figure.<br>
• 75% of total squares = \(\frac{75}{100} \times \text{Total} = \frac{3}{4} \times \text{Total}\).<br>
• Number to add = Target shaded squares - Currently shaded squares.<br><br>
From the figure: 8 more squares must be shaded to reach 75%.<br><br>
Final Answer: 8
