In the previous post we have discussed about Fractions and In today's session we are going to discuss about What is a Ratio, When we need to compare the two quantities, we say that we are going to find the ratio of the two numbers. Now let us learn what is a Ratio? We say that a ratio shows the relative sizes of two or more values. We can represent the ratio of the two quantities in different ways. First method to show the ratio is by colon sign “:”. Here we write two items separated by a colon. Another way to represent the ratio is as a single number by dividing one value by the total. If we take the examples of both the cases, we say that:
If there are 25 boys and 17 girls in the class and we need to represent the ratio of boys: girls, we write 25 ratio 17 or it can be expressed as 25 :17
In case we write there is one boy and 3 girls, then we represent the ratio as 1 : 3 and we write that for every 1 boy, there are 3 girls.
The above mentioned statement tells that there are in all 1 + 3 students, so we can also represent the above ratio as ¼ are boys and ¾ are girls. Here we can say that out of total of 4 children, we have 1 out of 4 as boys and 3 out of 4 as girls.
So on dividing ¼, we get 0.25 are boys and 0.75 are girls. This statement leads us to the conclusion that 25 % of all the students are boys and 75 % of all the children are girls.
