If you think of the "for every" as a : then it will make sense. So, replace the "for every" with a :.
So:
There are 5 strawberries for every 6 apples
Turns into
strawberries:apples = 5:6
So:
There are 5 strawberries for every 6 apples
Turns into
strawberries:apples = 5:6
For every means for example if there is going to be one apple there will always have to be 2 orananges so every time one apple adds there will be always 2 oranges
