Explain with words and examples how to convert 3 minutes and 20 seconds into all seconds. Also, how would you write 3 minutes and 20 seconds as a fraction or mixed number?
First, you start with finding how many seconds are in a minute and set up your equation.

Writing 3 minutes and 20 seconds as a mixed number is 3 20/60 which can be reduced to 3 1/3 seconds.
