Solve for x: x = 7700 / 88
Calculate: x ≈ 87.5

Therefore, 77 is approximately 87.5% of 88.

Method 2: Using Decimal Conversion

This method involves converting the fraction into a decimal and then multiplying by 100 to find the percentage.

Create a fraction: 77/88
Convert to a decimal: Divide 77 by 88. This equals approximately 0.875
Convert to a percentage: Multiply the decimal (0.875) by 100. This equals 87.5%

This confirms our previous result.
