Answer 1

2/3+ 25% - 5/6 : 10

= 2/3 + 1/4 - 5/6 :10

= 2/3+ 1/4 -1/12

= 8/12 + 3/12 - 1/12

= 11/12 -1/12

= 10/12= 5/6

Answer 2

\(\frac{2}{3}+25\%-\frac{5}{6}:10\)

=\(\frac{2}{3}+\frac{1}{4}-\frac{5}{6}.\frac{1}{10}\)

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

=\(\frac{8}{12}+\frac{3}{12}+\frac{1}{12}\)

= 1

Answer 3

\(\frac{2}{3}+25\%-\frac{5}{6}:10\)

\(=\frac{2}{3}+\frac{1}{4}-\frac{5}{6}.\frac{1}{10}\)

\(=\frac{11}{12}-\frac{1}{12}=\frac{10}{12}=\frac{5}{6}\)
