<h3>What is a Ratio?</h3>
A ratio shows us the number of times a number contains another number.
The need for barley in 200 ml of milk is 30 grams, therefore, the need for barley in 1 ml of milk can be written as,
Need of barely in 1 ml of milk = 30/200
Now, the amount of barely that will be needed for 300 ml of milk will be,
The amount of barely in 300 ml of milk = (30/200)×300 = 45 grams.
Hence, the amount barely needed for 300 ml of milk is 45 grams.
