A stone is projected with a velocity u such that it reaches height h. Find the ratio of its kinetic energy and potential energy when it is at a height 3h/4 from the ground. (potential energy is zero at the point of projection)

Can anyone do this for me? Please show the steps.

I think the answer should be 1:3
at first conservation of energy we get u^2=2gh
then by vertical motion of under gravity we can find at a height 3h/4 its kinetic energy will be mgh/4 and potential energy will be simply 3mgh/4 now you can find the ratio
