The problem shows $0.\overline{715}$, which represents a repeating decimal where the digits "715" repeat indefinitely.

To convert this repeating decimal into a fraction, we can follow these steps:

Step 1: Define the repeating decimal as a variable.

Let: $x = 0.\overline{715}$

Step 2: Multiply by a power of 10 to shift the decimal.

Since "715" is a three-digit repeating block, multiply both sides by $10^3 = 1000$: $1000x = 715.\overline{715}$

Step 3: Subtract the original equation from this new equation.

Subtract $x = 0.\overline{715}$ from $1000x = 715.\overline{715}$: $1000x - x = 715.\overline{715} - 0.\overline{715}$ This simplifies to: $999x = 715$

Step 4: Solve for $x$.

$x = \frac{715}{999}$

Step 5: Simplify the fraction.

The greatest common divisor (GCD) of 715 and 999 is 13, so divide both the numerator and denominator by 13: $x = \frac{715 \div 13}{999 \div 13} = \frac{55}{77}$

Thus, $0.\overline{715} = \frac{55}{77}$.
