'I' will toggle between the Irix and Solaris modes. 

"Also  for  multi-processor environments, if Irix mode is Off, top will 
operate in Solaris mode where a task's cpu usage will be divided by the 
total  number of CPUs.  You toggle Irix/Solaris modes with the `I' 
interactive command."

"System Monitor' on Ubuntu has a toggle and defaults to dividing; top 
defaults to Irix. He may not have had 'Show All Processes' set in System 
Monitor but a person in r/Ubunutu couldn't figure out what was bogging 
down the machine. top showed it was a service for video/gaming. 

'1' in top will show usage by core, although it's not the most intuitive 
presentation.  htop has a better presentation as far as cores but isn't as 
straight forward for processes. 

I hate to say it but Windows tools are a bit more polished.
