Math

In math we are working on Ratios. a ratio is a comparison of two numbers. a ratio looks like this 4:5. there are three different ways to put a ratio. 4:5, 4/5 and 4 to 5. ratios can be on a clock, in sports,field trips, how many boys and girls, the airport and video games.


ex: there are 8 girls and 12 boys in our class. so the ratio for girls to boys is 8:12. the ratio for boys to girls is 12:8.
