If I know the ratio of two variable differences, how to write it as a percentage increase?

Question

I know that $ \dfrac{\delta x}{ \delta y} = 5.8,$ meaning that the change in $x$ is $5.8$ times the change in $y.$

Is there a way to write this as a percentage increase? For example, there is a '$p$' percent increase in the change in $x$ compared to the change in $y.$
