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.

[ y + z ] / z    =    y/z  + z/z    =  y/z + 1  =   3/4 + 1   =  7/4

To figure out y+z, we can get the value of y and z from the second fraction. That is 3+4 which is 7. We know z is 4 from the denominator of the second fraction. 7/4 is the answer.
