Answer 2

Answer:

∴ $115$ can be divide as $51.15$ and $63.85$ in the ratio $4:5$.  

Step-by-step explanation:

• In context with question asked,
• We have to divide $115$ in the ratio $4:5$.
• Let, $115$ be divided into $4x$ and $5x$.
• So, according to given data, the equation becomes,

            $4x+5x=115$

                  ∴ $9x=115$

                    ∴ $x=\frac{115}{9}$

                    ∴ $x=12.77$

• Now, $4x=4\times 12.77=51.15$

       $5x=5\times 12.77=63.85$

• ∴ $115$ can be divide as $51.15$ and $63.85$ in the ratio $4:5$.
