To determine which number would make the statement \( \frac{5}{7} \cdot x > \frac{5}{7} \) true, we can simplify it.
Dividing both sides of the inequality by \( \frac{5}{7} \), we need to remember that dividing by a positive number does not change the inequality sign:
\[ x > 1 \]
Now we can evaluate the options you provided:
- \( \frac{17}{8} \): This is greater than 1 (since \( 17 \div 8 = 2.125 \)).
- \( \frac{4}{5} \): This is less than 1 (since \( 4 \div 5 = 0.8 \)).
- \( \frac{3}{3} \): This equals 1 (since \( 3 \div 3 = 1 \)).
- \( \frac{4}{9} \): This is also less than 1 (since \( 4 \div 9 \approx 0.444 \)).
The only option that satisfies the inequality \( x > 1 \) is:
\( \frac{17}{8} \).
