Understanding the Problem

The question "What percent of 75 is 3?" asks us to find the percentage that 3 represents when considering 75 as the whole or 100%. We need to determine what fraction 3 is of 75 and then convert that fraction into a percentage.

Method 1: Using Proportions

This method utilizes the concept of proportions to solve the problem. We can set up a proportion where:

• x represents the unknown percentage.
• 3 represents the part.
• 75 represents the whole.

The proportion is set up as follows:

x/100 = 3/75

To solve for x, we cross-multiply:

75x = 300

Then, divide both sides by 75:

x = 300 / 75

x = 4

Therefore, 3 is 4% of 75.

Method 2: Using Decimal Conversion

This method involves converting the fraction representing the parts to a decimal and then converting the decimal to a percentage.

1. Find the fraction: The fraction representing the parts is 3/75.

2. Convert to decimal: Divide 3 by 75: 3 ÷ 75 = 0.04

3. Convert to percentage: Multiply the decimal by 100: 0.04 x 100 = 4%

Therefore, 3 is 4% of 75.

Method 3: Using the Percentage Formula

The general formula for calculating percentages is:

(Part / Whole) * 100 = Percentage

In this case:

(3 / 75) * 100 = Percentage

(0.04) * 100 = 4%

This confirms that 3 is 4% of 75.
