Given data:
The first expression is 1/4 x 36.
The second expression is 5/8 x 36.
The firts expression can be written as,
[tex]\frac{1}{4}\times36=9\ldots\ldots\text{.(I)}[/tex]The second expression can be written as,
[tex]\begin{gathered} \frac{5}{8}\times36=\frac{5}{2}\times9 \\ =\frac{45}{2} \end{gathered}[/tex]The 7/8 x 36 can be written as,
[tex]\frac{7}{8}\times36=(\frac{1}{4}\times36)\times\frac{7}{2}[/tex]Substitute from equation (I).
[tex]\begin{gathered} \frac{7}{8}\times36=9\times\frac{7}{2} \\ =\frac{63}{2} \end{gathered}[/tex]Thus, the value of firts expression is 9 and second expression is 45/2.
