To find the equivalent fraction, we need to determine the value that makes the two fractions equal. We can do this by setting up a proportion and solving for the unknown numerator.
Step 1: Set Up the Proportion
We start with the given fractions:
\[
\frac{6}{8} = \frac{x}{80}
\]
Step 2: Cross-Multiply to Solve for \( x \)
To find the unknown numerator \( x \), we cross-multiply:
\[
6 \times 80 = 8 \times x
\]
Step 3: Simplify the Equation
Simplify the equation to solve for \( x \):
\[
480 = 8x
\]
Step 4: Solve for \( x \)
Divide both sides by 8:
\[
x = \frac{480}{8} = 60
\]
Final Answer
The equivalent fraction is:
\[
\frac{6}{8} = \frac{60}{80}
\]
\(\boxed{60}\)
