Introduction

In this article, we will explore the concept of percentages and how to use them to solve problems. We will focus on finding a number that is represented as a percentage of another number. Specifically, we will solve the problem: 1.6 is $8%$ of what number?

Understanding Percentages

To solve this problem, we need to understand what percentages are. A percentage is a way to express a value as a fraction of 100. For example, $8%$ means 8 out of 100, or $\frac{8}{100}$.

Converting Percentages to Decimals

To make calculations easier, we can convert percentages to decimals. To do this, we divide the percentage by 100. So, $8%$ is equal to $\frac{8}{100}$, which is equal to 0.08.

Setting Up the Equation

Now that we have converted the percentage to a decimal, we can set up an equation to solve the problem. We know that 1.6 is $8%$ of a certain number, so we can write an equation:

1.6=0.08x1.6 = 0.08x

where $x$ is the number we are trying to find.

Solving the Equation

To solve for $x$, we can divide both sides of the equation by 0.08:

1.60.08=x\frac{1.6}{0.08} = x

Calculating the Value

Now, we can calculate the value of $x$:

x=1.60.08x = \frac{1.6}{0.08}

x=20x = 20

Conclusion

Therefore, 1.6 is $8%$ of 20.
