Ratio

Almost at the end of the second round of the year, In math class we had learned about Ratio. What does ratio mean? Ratio mean to compare the number of something to the number of something. 

Example: If I want to compare boys, and girls students. I know that, there are 110 students in Liger with equally same amount of gender. If it is same amount of boys to girls, I know that, there are 55 boys, 55 girls. To ratio the number of boys to girls is 55 to 55 or 55:55, which both can be use. When we do the ratio, we need to you the number of something to the number of others thing. 

Ratio can do with more object, not just two object. It can be three, four, five or many object. d

Example: Engtieng has $5, Cheata has $4, David has $6, and Visal has $2. Why the ratio of Engtieng, Cheata, David, and Visal money. So we need to put in order list the amount of money down. Ratio of the money is 5:4:6:2, which 5 to 4 to 6 to 2.
