something like this should work:

- hosts: groupof10  
&nbsp;&nbsp;tasks:  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;- mail: subject='less than 20% root' ....  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;when: (root.size\_available / root.size\_total) \<= 0.20  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;vars:  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;root: "{{ansible\_mounts|selectattr('mount', 'equalto', '/')|first}}"
