hint:
you have to do this computation please:
\[\huge \frac{{15}}{{100}} \times 80 = ...?\]
since the exercise, asks for a portion of those 80 units
OpenStudy (anonymous):
I get different answers...over and above the number eighty.
OpenStudy (michele_laino):
what are your options, please?
OpenStudy (anonymous):
There are no options
