And the equation is this

anonymous · Answer

Harry has a jar that contains 75% of apple juice and the rest water. The bottle has 1 liter of water.

anonymous · Answer

Define the variable used in the equation. 
Well you know apple juice = 75% so water = 25% 
Keep in mind that percentage is the number over 100. 
So when you have 75% of apple juice, 
it means you have 75/100 of apple juice from the total mixture of apple juice and water. 
The same applies for 25% water.
