Steps to find the percentage of a number

Method 1: Using Proportions

Let's find 18% of 1 using proportion.

18% is 18 out of 100.

\[ \frac{ 18 }{100} \]

Write the proportion to find x out of 1.

\[ \frac{ 18 }{100} = \frac{x}{ 1 } \]

Cross-multiply: 18 × 1 = 100x

\[ 18 \cdot 1 = 100x \]

Solve for x: (18 × 1) ÷ 100 = x

\[ \frac{ 18 }{100} = x \]

Hence, 18% of 1 is 0.18.

Method 2: Keyword-Based

Use keywords: "of" means multiply.

Convert 18% to decimal: 0.18

\[ x = 1 \cdot 0.18 \]

Multiply 1 × 0.18 = 0.18

So, 18% of 1 is 0.18.

Method 3: Formula-Based

Use the formula: percent × whole = part

Convert 18% to decimal: 0.18

\[ \text{Percentage} \cdot \text{Whole} = \text{Part} \]

1 × 0.18 = 0.18

Thus, 18% of 1 is 0.18.
