Let's begin by identifying key information given to us:
I. One-third the sum of 6 and 3 is:
[tex]\begin{gathered} \frac{1}{3}\times(6+3) \\ \end{gathered}[/tex]II. Four times the quotient of 3 and 4 is:
[tex]4\times(\frac{3}{4})[/tex]III. One fourth the difference between 3 1/2 and 1/2 is:
[tex]\frac{1}{4}\times(3\frac{1}{2}-\frac{1}{2})[/tex]
