Count total parts in the circle. Find how many should be coloured for \( \frac{3}{4} \). Subtract the already coloured parts.<br><br>
• Count the total number of equal parts in the circle.<br>
• Multiply the total parts by \( \frac{3}{4} \) to find the target number of coloured parts.<br>
• Count the parts already coloured and subtract from the target.<br>
• More parts needed = 6<br>
<br>
Final Answer: D: 6
