Just a quick math question...

Alright so i think i know how to do this but i want to make sure completely so theirs no errors in my next grow, so say a bottle of nutrients says 5mL for every 22L of water, but you only have 5L of water. How would you caculate how many ml to use for 5L of water.

5/22 = .227272727272727

.227272727272727 * 5 = 1.13636363636363 (<----the answer)

let's check our work:

1.136363636363/5 = .22727272727272727

our work checks out.
