Question

What is the solution to r over three is equal to one over two?

Answer 1

\[\frac{ r }{ 3 }=\frac{ 1 }{ 2 }\]
We would first start off by cross multiplying;
\[2r=1(3)\]
\[2r=3\]
Now to get r alone on one side, we would divide both sides by 2;
\[\frac{ 2r }{ 2 }=\frac{ 3 }{ 2 }\]
\[r=\frac{ 3 }{ 2 }\]
\[r=1.5\]

Answer 2

you mean 1.6?

Answer 3

\[1.5\times2=3\]
\[1.6\times2=3.2\]
