ok, the question is to express:$4(\frac{z}{8})+\frac{z}{2}$as:$\frac{4z}{A}$

3. anonymous

btw the answer is not 8 or 1

4. asnaseer

so start by simplifying the first expression as follows:$4(\frac{z}{8})+\frac{z}{2}=\frac{z}{2}+\frac{z}{2}=z$now, the only way that $$\frac{4z}{A}=z$$ is if A=4

5. asnaseer

I need to go now - hopefully you understood the method above.
