If -84−84 is less-than (<)(<) 7c7c, then 7c7c must be higher in value than -84−84.
So 77 multiplied by what = -84=−84? Using a calculator, trial and error, or by dividing -84−84 by 77, you will find that
7 * (-12) = -847⋅(−12)=−84
So your answer is: 'cc is more than -12−12' OR 'c > -12c>−12' as any number higher in value than -12−12 could equal cc.
Hope this helps!
