I have a ridiculous problem I need help with:

If A:0,6m2 consumes B:0,95ml of something (say paper consumes water i.e.) how can I use these numbers to calculate any m2 to get the ml consumption? I want to know how much 1m2 consumes, based on that relation.

I know this is simple, but I can't for the life of me remember how. I would greatly appreaciate any help.

    $\begingroup$ You want the quantity "consumption per square meter" assuming it's linear? Well, 0.6m^2 consumes 0.95ml so 0.1m^2 consumes 0.95/6 ml and 1m^2 consumes 9.5/6 ml. $\endgroup$ – saldukoo Aug 24 '16 at 9:45
