+34 \(\text{Suppose }\frac{x}{y}=\frac{5}{7} \text{and }\frac{y}{z}=\frac{3}{4}. \)
\( \text{What is the value of } \frac{y+z}{z}?\)
\( \text{ Express your answer as a common fraction.}\)
+4609 Does this say \(\frac{y+z}{z}\) . If so, try to break it up into \(\frac{y}{z}+\frac{z}{z}\)\(\) , so \(\frac{y}{z}+1.\)\(\) Therefore, we have \(4y=3z, y=\frac{3}{4}z\) and \(\frac{3z}{4}*\frac{1}{z}=\frac{3}{4}\)\(\) , so \(1+\frac{3}{4}=\boxed{1\frac{3}{4}}.\)
