Imagine you want to compare the numbers of women and men in the entire globe, but there are billions and billions of them. How can you easily compare those big numbers?
Well, Ratio is our solution in this case. “Ratio” is the comparison of two numbers in relevant to each other in the simplest form. Back to our problem, the ratio of women and men can be 1:4(one to four)meaning the number of men is 4 times greater than the number of women.

Ratio allows us to compare two related numbers easily and it helps us to understand the comparison faster in the simplest form.
What do I mean when I say the simplest form? For example, in math class, there are 20 girls and 30 boys. We can say the ratio of girls to boys is 2:3 because we divided 20 by 10 and 30 by ten and we get its simplest form. If we want to make the number as its simplest form, we need to divide both numbers with the same number just like the upper example.
Ratio is very useful when it comes to cooking. It allows us to cook in any size of the meal using the same formula. For example, the recipe is created for a 2 people meal but you want to cook that meal for a big party, you can look up its ratio and just multiply the number to make it suitable for your situation.
For example, we need 2 eggs and 3 kilograms of flour(The ratio of eggs to flour is 2:3)to cook for 2 people. If you are using that same recipe for 18 people, you can multiply 2 with 18 and 3 with 18 to follow the ratio.
