To convert the repeating decimal \( x = 0.264\overline{264} \) to a rational number, you'll want to eliminate the repeating part. In this case, the digits "264" repeat.
### Step 1: Set up the equation
Let \( x = 0.264264264\ldots \)
### Step 2: Determine the multiplier
Since "264" has 3 digits, you will multiply both sides of the equation by \( 1000 \) (which is \( 10^3 \)) to shift the decimal point 3 places to the right:
\[
1000x = 264.264264264\ldots
\]
### Step 3: Set up a second equation
Now, you also have the original value of \( x \):
\[
x = 0.264264264\ldots
\]
### Step 4: Subtract the two equations
Now you can subtract the two equations:
\[
1000x - x = 264.264264264\ldots - 0.264264264\ldots
\]
This simplifies to:
\[
999x = 264
\]
### Step 5: Solve for \( x \)
Now, divide both sides by 999:
\[
x = \frac{264}{999}
\]
### Conclusion
So, to convert \( 0.264\overline{264} \) to a rational number, you multiply both sides of the equation by **1000**.
### Step 1: Set up the equation
Let \( x = 0.264264264\ldots \)

\]
This simplifies to:
\[
999x = 264
\]
### Step 5: Solve for \( x \)
Now, divide both sides by 999:
\[
x = \frac{264}{999}
\]
### Conclusion
So, to convert \( 0.264\overline{264} \) to a rational number, you multiply both sides of the equation by **1000**.
