If you have a square that is divided into 4 equal parts, and 3 of those parts are shaded, then to find the percentage of the square that is shaded, you can use the following calculation:
- Determine the number of parts shaded: 3
- Determine the total number of parts: 4
- Calculate the fraction that is shaded: \( \frac{3}{4} \)
- Convert the fraction to a percentage: \[ \left( \frac{3}{4} \right) \times 100 = 75% \]
So, 75% of the square is shaded.
