To determine which number would make the inequality \( \frac{5}{7} \cdot x > \frac{5}{7} \) true, we can simplify the inequality.
-
Start with the inequality: \[ \frac{5}{7} \cdot x > \frac{5}{7} \]
-
To isolate \( x \), we can divide both sides by \( \frac{5}{7} \) (noting that since \( \frac{5}{7} > 0 \), the inequality doesn't change direction): \[ x > 1 \]
Now we need to evaluate the options given:
- \( \frac{4}{9} \) (which is less than 1)
- \( \frac{3}{3} = 1 \)
- \( \frac{17}{8} \) (which is greater than 1)
- \( \frac{4}{5} \) (which is less than 1)
The only option that satisfies the inequality \( x > 1 \) is \( \frac{17}{8} \).
Thus, the correct answer is:
17/8
