The **ratio **notion is used in **mathematics **when evaluating two or more numbers. It works as a **comparison **tool to **demonstrate **how big or small a particular **number **is. A ratio **divides **two **quantities **in order to compare them.
As per the given information provided in the question,
The **total **number of **boys **and **girls **on tour is 90
Let the number of **boys **be 6x and the number of **girls **be 3x .
6x + 3x = 90
9x = 90
x = 10
Then, the number of girls will be,
3x = 3 (10) = 30 .

In a group of 90 students with a ratio of girls to boys of 3:6, there are 30 girls. This is calculated by using a variable to represent the common multiplier in the ratio and solving the resulting equation. The total number of students is then used to find the number of girls.
