Question

What number could replace z below 3/z=9/12

Answer 1

The value of z is 4

Explanation:

We have the following expression:

`(3)/(z)=(9)/(12)`

To know the value of z we must solve for z in the expression just like this:

`\begin{gathered} 12\cdot3=9\cdot z \\ z=(36)/(9) \\ z=4 \end{gathered}`
