The question asks for "80% of 55."  

 

"Of" is an indicator for the multiplication indicator. You can replace it. We have now changed the question to \(80\% *55\). Now, let's evaluate it!

 

\(80\% *55\) In general, \(a\%=\frac{a}{100}\).
\(\frac{80}{100}*\frac{55}{1}\) Let's simplify 80/100 to simplest terms by realizing that the numerator and denominator have a greatest common factor of 20.
\(\frac{4}{5}*\frac{55}{1}\) To faciliate the computational process even more, notice that 5 and 55 havea  GCF of 5.
\(\frac{4}{1}*\frac{11}{1}\) Now, do the multiplication.
\(44\)  
   

 

Therefore, 80% of 55 is 44.
