if there are 300 toffees then if we want to distritibute among 5:6 of ravi and shivam then how much tofee will shivam get

Suppose Ravi get 5x toffees while Shivam get 6x tofees.
Total number of toffees distributed = 300
So we have;
$$\begin{gathered} 5x+6x = 300 \\ \Rightarrow 11x = 300 \\ \Rightarrow x = \frac{300}{11} \end{gathered}$$
So number of toffees that Shivam get = $6\times \frac{300}{11} = \frac{1800}{11} = 163.636\approx 164$
Therefore Shivam get an approximately 164 toffees.
