Question

\(\frac{6}{8}\)-    \(\frac{2}{3}\)

Answer 1

TA CÓ: \(\frac{6}{8}\)= \(\frac{3}{4}\)

\(\frac{3}{4}\) - \(\frac{2}{3}\) = \(\frac{9-8}{12}\)= \(\frac{1}{12}\)

Answer 2

\(\frac{6}{8}\)-  \(\frac{2}{3}\)

\(\frac{2}{3}\)=  \(\frac{2x2}{3x2}\)=    \(\frac{4}{6}\)

\(\frac{6}{8}\)-  \(\frac{2}{3}\)=\(\frac{6}{8}\)-  \(\frac{4}{6}\)=  \(\frac{6-4}{8-6}\)= \(\frac{2}{2}\)=\(1\)

Answer 3

\(40x2=80\)
