If x/y = 1/9 and y/z = 9/8 then z/x = ?

a) 1/648
b) 1/8
c) 8/81
d) 81/8
e) 8

could you explain how to do this.

OK. If you need to find the equal equation for z/x you have to take the parts from other equations. so you know that z=8 and x=1 so z/x= 8 over 1=8/1= 8/1 once simplified equals 8. Your pretty much taking the numbers along that you need for the equation.

W-14=t. that i think is the answer idk
