Ratio shows the relationship that exists between two or more more numbers. It is the frequency of the number of times that one number is contained in other numbers.
The ratio of teaspoons of mustard seeds, chilli powder and salt in the recipe is 3:5:1. These means that for every batch made, 3 teaspoon of mustard seed, one teaspoon of salt and five teaspoons of chilli powder is used.
If two batches are made, the ratio becomes : 2( 3 : 5 : 1) = 6: 10: 2.
If three batches are made, the ratio becomes : 3( 3 : 5 : 1) = 9 : 15 : 3
