What is a proportion problem in math?

A proportion is an equation in which two ratios are set equal to each other. For example, if there is 1 boy and 3 girls you could write the ratio as: 1 : 3 (for every one boy there are 3 girls) 1 / 4 are boys and 3 / 4 are girls. 0.25 are boys (by dividing 1 by 4)

How do I teach proportions?

Work with these tables (first using easy numbers) until the students get used to them. You can tie in some of them with real-life situations.
