Understanding the Basics of Percentages

Before diving into the calculation, let's refresh our understanding of percentages. A percentage is a fraction expressed as a number out of 100. For example, 50% means 50 out of 100, or 50/100, which simplifies to 1/2.

Method 1: Using the Fraction Method

The most straightforward method to find what percentage 9 out of 16 is involves converting the fraction 9/16 into a percentage. Here's how:

1. Express as a fraction: We start with the fraction 9/16. This represents 9 parts out of a total of 16 parts.

2. Convert to a decimal: Divide the numerator (9) by the denominator (16): 9 ÷ 16 = 0.5625

3. Convert to a percentage: Multiply the decimal by 100: 0.5625 x 100 = 56.25%

Therefore, 9 out of 16 is 56.25%.

Method 2: Using Proportions

Another approach involves setting up a proportion:

1. Set up the proportion: We can represent the problem as a proportion: 9/16 = x/100, where 'x' represents the percentage we're trying to find.

2. Cross-multiply: Cross-multiply to solve for x: 16x = 900

3. Solve for x: Divide both sides by 16: x = 900 ÷ 16 = 56.25

Again, this confirms that 9 out of 16 is 56.25%.
