5/11 . 3/17 + 5/11 . 8/17

Answer 1

\(\dfrac{5}{11}\cdot\dfrac{3}{17}+\dfrac{5}{11}\cdot\dfrac{8}{17}=\dfrac{5}{11}\cdot\left(\dfrac{3}{17}+\dfrac{8}{17}\right)=\dfrac{5}{11}\cdot\dfrac{11}{17}=\dfrac{5}{17}\)

Answer 2

5/11 . 3/17 + 5/11 . 8/17

\(=\dfrac{5}{11}.\left(\dfrac{8}{17}+\dfrac{3}{17}\right)=\dfrac{5}{11}.\dfrac{11}{17}=\dfrac{5}{17}\)

 

Answer 3

\(=\dfrac{5}{11}.\left(\dfrac{3}{17}+\dfrac{8}{17}\right)=\dfrac{5}{11}\cdot\dfrac{11}{17}=\dfrac{5}{17}\)

Answer 4

\(=\dfrac{5}{11}\times\left(\dfrac{3}{17}+\dfrac{8}{17}\right)\\ =\dfrac{5}{11}\times\dfrac{11}{17}\\ =\dfrac{5}{17}\)
