Core Mathematics - Dilution factors

Dilution factors

Many chemicals or drugs are too strong to use in their concentrated form.
Distilled water is often used to dilute the drugs to the required
concentration. In the following example a medicine needs to be diluted by
putting in 30 ml to get 1 L of mixture. How much medicine is needed to make
135 ml of the mixture?

Each of the three containers above has two taps (nozzles). 1) Click on
the taps, 2) Fill the containers with water and concentrate and 3) Explore
ratios.
