A ratio is a comparison of two numbers. Place 2 red tiles and 5 blue tiles. The number of red tiles to blue tiles can be written as the ratio 2:5. Double the number of tiles to create the ratio 4:10. A proportion is an equation that shows that two ratios are equal. The ratios 2:5 and 4:10 form a proportion because their ratios are equivalent.
