Answer 1

initially the kettle has 20 3/8 cups of soda
5/8 is taken away by the server

so essentially your problem is (20 3/8) - 5/8

there's 2 ways you could approach this:
- convert 20 3/8 into an improper fraction

(multiply the denominator by the whole number, then add the numerator, then put it all over the denominator.)

- breakr down 5/8 into 3/8 and 2/8.
start with 20 and 3/8, take away 3/8 to get 20, then subtract another 2/8 from 20 to get the final result

Answer 2

I got -79/4
