Steps to find the percentage of a number

Method 1: Using Proportions

Let's find 100% of 4.5 using proportion.

100% is 100 out of 100.

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

Write the proportion to find x out of 4.5.

\[ \frac{ 100 }{100} = \frac{x}{ 4.5 } \]

Cross-multiply: 100 × 4.5 = 100x

\[ 100 \cdot 4.5 = 100x \]

Solve for x: (100 × 4.5) ÷ 100 = x

\[ \frac{ 450 }{100} = x \]

Hence, 100% of 4.5 is 4.5.

Method 2: Keyword-Based

Use keywords: "of" means multiply.

Convert 100% to decimal: 1

\[ x = 4.5 \cdot 1 \]

Multiply 4.5 × 1 = 4.5

So, 100% of 4.5 is 4.5.

Method 3: Formula-Based

Use the formula: percent × whole = part

Convert 100% to decimal: 1

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

4.5 × 1 = 4.5

Thus, 100% of 4.5 is 4.5.
