2/3-(1/6+1/8)=2/3-7/24=16/24-7/24=9/24
\(\frac{2}{3}-\left[\frac{1}{6}+\frac{1}{8}\right]\)
\(=\frac{2}{3}-\left[\frac{8}{48}+\frac{6}{48}\right]\)
\(=\frac{2}{3}-\frac{7}{24}\)
\(=\frac{16}{24}-\frac{7}{24}\)
\(=\frac{3}{8}\)
\(\frac{2}{3}-\left(\frac{1}{6}+\frac{1}{8}\right)\)
\(=\frac{2}{3}-\frac{7}{24}\)
=\(\frac{3}{8}\)
\(\frac{2}{3}-\left(\frac{1}{6}+\frac{1}{8}\right)\)
\(=\frac{2}{3}-\left(\frac{8}{48}+\frac{6}{48}\right)\)
\(=\frac{2}{3}-\frac{7}{24}\)
\(=\frac{16}{24}-\frac{7}{24}\)
\(=\frac{3}{8}\)
