Good afternoon! Today, we began our unit on ratios and rates. Ratios are a comparison of two different amounts. They can be written three different ways (see the first video). A rate is an amount or frequency measured against another amount or frequency. A unit rate (unit means "one" or "per") is an amount or frequency compared to one of something.
For example, the going rate on a 2-liter bottle of soda might be $1.98 / 2 liters. The unit rate for this same bottle of soda would be $0.99 per (one) liter.
Another example of how rates and unit rates are related might be when you are traveling. If Mary travels at a unit rate of 60 miles per hour in her car, how far would that be in 5 hours at that exact same rate of speed? The new rate would be the Mary traveled 300 miles / 5 hours of time.
Check out the information below to further assist in understand ratios, rates, and unit rates. As always, feel free to email me if extra help is needed!
Thanks for stopping by and have an awesome day!
