Answer 1

(4/11+7/11)*5/6

=1*5/6=5/6

Answer 2

5/6.(4/11+7/11)

=5/6.1

=5/6

Answer 3

5/6 x (4/11 + 7/11) = 5/6 x 1 = 5/6

Answer 5

5/6 x (4/11 + 7/11)

= 5/6 x 1 = 5/6

Answer 6

(\(\dfrac{4}{11}\)+\(\dfrac{7}{11}\))*\(\dfrac{5}{6}\)

=1*\(\dfrac{5}{6}\)=\(\dfrac{5}{6}\)

Answer 7

     \(\dfrac{5}{6}\cdot\dfrac{4}{11}+\dfrac{5}{6}\cdot\dfrac{7}{11}\)

\(=\dfrac{5}{6}\cdot\left(\dfrac{4}{11}+\dfrac{7}{11}\right)\)

\(=\dfrac{5}{6}\cdot\left(\dfrac{4+7}{11}\right)\)

\(=\dfrac{5}{6}\cdot1\)

\(=\dfrac{5}{6}\)
