Question

Is 6/8 bigger than 1/2

Answer 1

Yes, 6/8 is bigger than 1/2 because 1/2 is technically 0.5. 
While 6/8 is more than one half. 

Answer 2

$\frac{6}{8}=\frac{6:2}{8:2}=\frac{3}{4}\\\\\frac{1}{2}=\frac{1\cdot2}{2\cdot2}=\frac{2}{4}\\\\\frac{3}{4} \ \textgreater \ \frac{2}{4}\ becvause\ \frac{3 \ \textgreater \ 2}{4=4}\\\\therefore:\\\frac{6}{8}\ is\ bigger\ than\ \frac{1}{2}$
