Question

Ratios and porporttions the problem is attached below as a file

Answer 1

a) Since

`(2)/(4)=(1)/(x)=(4)/(y)=(50)/(z)`

Then,

`\begin{gathered} \Rightarrow(2)/(4)=(1)/(x)\Rightarrow x=(4)/(2)\Rightarrow x=2 \\ \Rightarrow(2)/(4)=(4)/(y)\Rightarrow y=4\cdot(4)/(2)=8\Rightarrow y=8 \\ \Rightarrow(2)/(4)=(50)/(z)\Rightarrow z=50\cdot(4)/(2)\Rightarrow z=100 \end{gathered}`

Thus, the answers to part a) are x=2, y=8, and z=100

b) Notice that 2/4=1/2=0.5, and 0.5=50%; therefore, 2/4 is equal to 50%.

c)
