Answer 1

Answer 2

x.(\(\dfrac{1}{6}\)+\(\dfrac{1}{10}\)+\(\dfrac{1}{15}\)+\(\dfrac{1}{21}\)+\(\dfrac{1}{28}\)+\(\dfrac{1}{36}\)+\(\dfrac{1}{45}\)+\(\dfrac{1}{55}\)+\(\dfrac{1}{66}\)+\(\dfrac{1}{78}\))=\(\dfrac{220}{39}\)

x.\(\dfrac{20}{39}\)=\(\dfrac{220}{39}\)

x=\(\dfrac{220}{39}\):\(\dfrac{20}{39}\)

x=11
