Answer 1

`1 1/36` cups to be added.

Explanation:

take 20 multiply by `1/9`
`20xx1/9 =(20xx1)/9`

=`20/9`

Then we change `3 1/4` into a improper fraction
It gives us `13/4`

First we change the fractions to the same denominator.
Then we subtract them.

`13/4 - 20/9`

`= 117/36 - 80/36`

=`37/36`

=`1 1/36`
