Suppose $\frac{x}{y}=\frac{5}{7}$ and $\frac{y}{z}=\frac{3}{4}$. What is the value of $\frac{y+z}{z}$? Express your answer as a common fraction.
HELP!!!
First of all you gotta chill out. The fraction can split into y/z + z/z, and the z/z can turn into 1, so you just have to calculate y/z+1. So can you solve it from now? the y/z is also in the question itself
