Step-by-step explanation:

If a cups scientist needs 12 cup baking soda for 45 liter of water, this can be expressed as;

12 cup of soda = 45 litres of water

To get the amount of soda needed for one litre, we will say;

x soda = 1 litre

Divide both equations;

12/x = 45/1

Cross multiply'45x = 12

x = 12/45

x = 4/15

Hence the required answer us 4/15 cups
