The ratio and its properties to solve real life problems.

In this video, students are challenged to find the number of girls in a school using a given ratio of girls to boys, which is 3 to 4, and the known number of boys, 140. The video demonstrates how to solve this problem by multiplying the ratio of girls by the number of boys and dividing by the ratio of boys. The solution reveals there are 105 girls. The video concludes by explaining how this method can be applied to other problems involving ratios and known quantities.
