In finding a number between 9/8 and 10/8, we can use the average of these two.
We can ensure that this number lies between this two.
[tex]Ave=\frac{1}{2}(a+b)[/tex]where a and b are the two numbers
So we have :
[tex]\begin{gathered} Ave=\frac{1}{2}\times(\frac{9}{8}+\frac{10}{8}) \\ =\frac{9}{16}+\frac{10}{16} \\ =\frac{19}{16} \end{gathered}[/tex]Therefore, one number that lies between 9/8 and 10/8 is :
[tex]\begin{gathered} \frac{19}{16} \\ or \\ 1\frac{3}{16} \end{gathered}[/tex]
