Finding what percent one number is of another is a common math problem. This article will show you how to calculate what percent 77 is of 88, step-by-step, and provide some helpful context. We'll even explore different methods to solve this type of problem.
Understanding the Problem
The core question is: 77 represents what percentage of 88? To solve this, we need to set up a simple equation.
Method 1: Using a Proportion
This is a classic approach to percentage problems. We set up a proportion:
- Part / Whole = Percentage / 100
In our case:
- 77 / 88 = x / 100
Where 'x' represents the percentage we're trying to find.
Now, we solve for 'x':
- Cross-multiply: 77 * 100 = 88 * x
- Simplify: 7700 = 88x
- 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.
Method 3: Using a Calculator (The Easiest Way!)
Most calculators have a percentage function. Simply enter 77 ÷ 88 × 100 to directly obtain the answer: 87.5%.
