To solve the inequality \( \frac{x}{13} < \frac{4}{5} \), we can start by multiplying both sides by 13 to eliminate the fraction.
\[ x < 13 \cdot \frac{4}{5} \]
Next, calculate \( 13 \cdot \frac{4}{5} \):
\[ 13 \cdot \frac{4}{5} = \frac{13 \cdot 4}{5} = \frac{52}{5} \]
Thus, we have:
\[ x < \frac{52}{5} \]
Therefore, the correct response is:
x < \frac{52}{5}
(x less than Start Fraction 52 over 5 End Fraction)
