117
EXPLANATION
A number is divided in the ratio 8 : 1 and the second part is 13.
The total ratio is:
8 + 1 = 9
Let the number divided be x.
This means that:
[tex]\frac{1}{9}\cdot\text{ x = 13}[/tex]Simplify:
[tex]\begin{gathered} \text{Multiply through by 9:} \\ x\text{ = 13 }\cdot\text{ 9} \\ x\text{ = }117 \end{gathered}[/tex]Therefore, the number is 117.
