Understanding Percentages

A percentage is a fraction expressed as a number out of 100. For example, 60% means 60 out of 100, or 60/100. This fraction can be simplified to 3/5.

Method 1: Converting Percentage to Decimal

This is the most common and straightforward method. We'll convert the percentage to a decimal and then multiply.

Steps:

  1. Convert the percentage to a decimal: To convert 60% to a decimal, divide by 100: 60 / 100 = 0.60

  2. Multiply the decimal by the number: Multiply the decimal (0.60) by the number you want to find the percentage of (120): 0.60 * 120 = 72

Therefore, 60 percent of 120 is 72\boxed{72}.

Method 2: Using Fractions

We can also solve this using fractions, based on our understanding of percentages as fractions.

Steps:

  1. Express the percentage as a fraction: 60% can be written as the fraction 60/100.

  2. Simplify the fraction (optional): 60/100 simplifies to 3/5.

  3. Multiply the fraction by the number: Multiply the simplified fraction (3/5) by 120: (3/5) * 120 = 72

Again, we find that 60 percent of 120 is 72\boxed{72}.

Method 3: Proportion Method

This method sets up a proportion to solve for the unknown value.

Steps:

  1. Set up a proportion: We can set up a proportion like this: x / 120 = 60 / 100, where 'x' represents the unknown value (60% of 120).

  2. Cross-multiply: Cross-multiply to get: 100x = 7200

  3. Solve for x: Divide both sides by 100: x = 7200 / 100 = 72

This confirms that 60 percent of 120 is 72\boxed{72}.
