# 17 is 25% of what number?

#### Understand the Problem

The question is asking for a number such that 17 is 25% (or a quarter) of that number. We can approach this by setting up an equation where we find the unknown number based on this percentage.

$68$

The unknown number is $68$.

#### Steps to Solve

1. Set up the equation

We start by letting the unknown number be represented by $x$. Since 17 is 25% of $x$, we can express this relationship as:

$$0.25 \cdot x = 17$$

1. Solve for $x$

To find $x$, we need to isolate it on one side of the equation. We can do this by dividing both sides of the equation by 0.25:

$$x = \frac{17}{0.25}$$

1. Calculate the value

Now, we calculate the right side:

$$x = 17 \div 0.25$$

1. Result

This simplifies to:

$$x = 68$$

The unknown number is $68$.

This means that if you take 25% of $68$, you will get $17$. It demonstrates how percentages can be converted into an equation to solve for an unknown quantity.
• Forgetting to divide when isolating $x$: Ensure to perform the division correctly when moving terms across the equation.
