What purpose do the commas serve in the following sentence? Danielle goes to dance class on Tuesday, Thursday, and Saturday.
To separate the days she goes to class. The commas are there to show that she goes to class on each of those days separately.
hope that helps:))
they are there because if u were to write a sentence on this u would have too many ands in the sentence so thats why they made up commas and they do what the word 'and' does hope this helped
