Jane has 12 litres of orange JUICE.

She needs 70 litres and the ratio is 1 litre of orange JUICE and 5 litres of water.

Does she have enough orange?



----
Concentration as a fraction is 1%2F6 Orange Juice.

x, litres Orange Juice
y, litres water

system%28x%2F70=1%2F6%2Cx%2By=70%29
If this makes good sense to you, then you are understanding. The rest is algebra.

If x is less than 12, then Jane does not have enough orange juice.

If the concentration and the ratio were the confusing parts, then 1 litre of OJ and 5 litres of water make total of 6 liters. The concentration as OJ is %281%2ApartOJ%29%2F%286%2ApartsWater%29=%281%2F6%29OJ. The x%2F70 shows amount of Orange juice as numerator and amount of what is the be prepared as denominator, the 70 litres total volume.
