For every 1 litre of water used to make a medicine, 300 ml of sucrose and 750ml of saline solution are used. express the amount of water, sucrose and saline solution needed as a ratio in its simplest form.

Required ratio will be 20:6:15.

Step-by-step explanation:

Since we have given that

For every 1 liter of water used to make a medicine, 300 ml of sucrose and 750 ml of saline solution are used.

So, We need to express the amount of water, sucrose and saline solution in its simplest form.

So, all amount will be in same units i.e. ml.

As we know that

So, Ratio will be expressed as

Hence, required ratio will be 20:6:15.
