Question

4/7. 5/6 + 4/7. 1/6

Answer 1

\(=\dfrac{4}{7}.\left(\dfrac{5}{6}+\dfrac{1}{6}\right)\\ =\dfrac{4}{7}.\dfrac{6}{6}\\ =\dfrac{4}{7}.1=\dfrac{4}{7}\)

Answer 2

\(\dfrac{4}{7}.\dfrac{5}{6}+\dfrac{4}{7}.\dfrac{1}{6}=\dfrac{4}{7}.\left(\dfrac{5}{6}+\dfrac{1}{6}\right)=\dfrac{4}{7}.1=\dfrac{4}{7}\)

Answer 3

`(4)/(7).(5)/(6)+(4)/(7).(1)/(6)`

`=(4)/(7).((5)/(6)+(1)/(6))`

`=(4)/(7).(6)/(6)`

`=(4)/(7).1=4/7`

Answer 4

\(\dfrac{4}{7}\cdot\dfrac{5}{6}+\dfrac{4}{7}\cdot\dfrac{1}{6}\)

\(=\dfrac{10}{21}+\dfrac{2}{21}\)

\(=\dfrac{4}{7}\)
