Chapter 7: Q5. (page 352)

Use a proportion to answer the question. What number is 18% of 50?

Short Answer

Expert verified

The value of 18% of 50 is 9.

Step by step solution

Step 1. Given Information.

The number is 50.

Step 2. Calculation.

Let $x$ be the number.

Write percentage as a fraction.

Therefore,

$\frac{x}{50} = \frac{18}{100}$

Multiply both sides of the equation by 50 to isolate the variable on one side of the equation.

$\begin{matrix} \frac{x}{50} \times 50 = \frac{18}{100} \times 50 \\ x = 9 \end{matrix}$

Step 3. Conclusion.

The value of 18% of 50 is 9.
