For every 1 litre of water used to make a medicine, 193ml of sucrose and 13ml of saline solution are used. Express the amount of water, sucrose and saline solution needed as a ratio in its simplest form.

1000:193:13

Step-by-step explanation:

Requirement of water to make a medicine = 1 litre = 1000ml;

Amount of sucrose = 193ml;

Amount of saline solution = 13 ml;

Ratio of Water: Sucrose: Saline Solution is;

1000:193:13

It cannot be simplified further.

Thus, 1000:193:13 is the simplest form of ratio of the solutions
