I know to ask,
Please, fill half a glass of water/tea.
Well, the context for the above sentence is understandable. But, what if I need to ask the same, where
The tea/water is more than half but not full.
It is less than half but neither empty nor very little.
Do we have any words/sentences to express for these two cases? I guess we can't say:
Please fill 25% or 37% of tea OR 75% of water
