Answer 1

-4/12 + 6/7 + 8/24

= (-4/12 + 8/24) + 6/7

= 0 + 6/7

= 6/7

Answer 2

\(-\frac{4}{12}+\frac{6}{7}+\frac{8}{24}\)

\(=-\frac{1}{3}+\frac{6}{7}+\frac{1}{3}\)

\(=\left(-\frac{1}{3}+\frac{1}{3}\right)+\frac{6}{7}\)

\(=0+\frac{6}{7}\)

\(=\frac{6}{7}\)

Answer 3

\(-\frac{4}{12}+\frac{6}{7}+\frac{8}{24}\)

\(=\left(-\frac{4}{12}+\frac{8}{24}\right)+\frac{6}{7}\)

\(=0+\frac{6}{7}=\frac{6}{7}\)

Answer 4

=-8/24+6/7+8/24

=6/7

Answer 5

\(\frac{-4}{12}+\frac{6}{7}+\frac{8}{24}\)

\(=\frac{-1}{3}+\frac{6}{7}+\frac{1}{3}\)

\(=\frac{-1}{3}+\frac{1}{3}+\frac{6}{7}\)

\(=0+\frac{6}{7}\)

\(=\frac{6}{7}\)

Answer 6

-4/12+6/7+8/24

=-1/3+6/7+1/3

=[(-1/3)+1/3]+6/7=0+6/7

=6/7

Answer 7

\(\frac{-4}{12}+\frac{6}{7}+\frac{8}{24}\)

\(=\frac{-1}{3}+\frac{6}{7}+\frac{1}{3}\)

\(=\frac{-1}{3}+\frac{1}{3}+\frac{6}{7}\)

\(=0+\frac{6}{7}\)

\(=\frac{6}{7}\)
