1/5x6 + 7/6 - 6/5 =

Answer 1

1/5 x 6 +7/6-6/5

=1/30+7/6-6/5

=1/30+35/30-36/30

=0/30

=0

Answer 2

    1/5x6 + 7/6 - 6/5 = 1/30 + 7/6 - 6/5

                               = 1/30 + 35/30 - 36/30

                               = 36/30 - 36/30

                               =0/30 = 0

Answer 3

  \(\frac{1}{5}\)x    6   +   \(\frac{7}{6}\)-    \(\frac{6}{5}\)

= \(\frac{6}{5}\) +     \(\frac{7}{6}\)   -    \(\frac{6}{5}\) 

= \(\frac{13}{5}\) -    \(\frac{6}{5}\)

=   \(\frac{7}{5}\)

Answer 4

\(\frac{1}{5}\cdot6+\frac{7}{6}-\frac{6}{5}\)

\(=\frac{1}{30}+\frac{7}{6}-\frac{6}{5}\)

\(=\frac{1}{30}+\frac{35}{30}-\frac{36}{30}\)

\(=\frac{0}{30}=0\)

Answer 5

1/5 x 6 + 7/6 - 6/5 = 1/30 + 7/6 - 6/5

                           = 1/30 + 35/30 - 36/30

                           = 36/30 - 36/30

                           = 0/30 = 0
