For every 1 litre of water used to make a medicine, 150 ml of sucrose and 600ml of saline solution are used. Express the amount of water, sucrose and saline solution needed as a ratio in its simplest form.

Quantity of water used to make a medicine :-

This quantity of water required to make a medicine = 1000 ml

Quantity of sucrose used to make a medicine = 150 ml

Quanity of saline solution used to make a medicine = 600 ml

The quantity of water to sucrose to saline solution needed to make a medicine as a ratio :-

Cutting each common zero in this ratio, we get :-

Dividing each number in the ratio by 5, we get the ratio :-

Since, the three numbers in this ratio doesn't have any common factors we can conclude that we have found out the simplest form of the ingredients needed to make the medicine .

Therefore, the ratio of water to sucrose to saline solution needed to make a medicine = 20:3:12

step-by-step explanation:

x -

median = 1.25

range = 12-14.5

interquartile = q12-q14.5

y -

median = 1

range = 15-17

interquartile = q15-q17
