Ratios


Today in math we did ratios. A ratio is a comparison of two numbers. There are 3 different ways to write ratios like: 4to5 -word form, 4:5 -ratio form, and 4/5 -fraction form. You can find ratios everywhere like clocks, scores in games, at the airport, shapes and on field trips.

Examples:
Write 6to7 two other ways: 6:7, and 6/7.

Also there is 9 girls in our class and 12 boys in our class so the ratio for that would be: 9:12, 9/12 and 9to12.
