`1(2)/(6)+3(2)/(6)+7(5)/(6)`

If x:y=3:4land a:b=1:2, then the value of (2xa+yb)/(3yb-4xa) is (5)/(6) b.(6)/(7) c.(6)/(5) d.(7)/(6)

2(1)/(7) + 3(6)/(7) + 5(1)/(6) = ?

5(1)/(4)+6(2)/(3)+7(1)/(6)=?

The projections of a vector on the three coordinate axis are 6,3,2 respectively.The direction cosines of the vector are (A)6,-3,2(B)(6)/(5),(-3)/(5),(2)/(5)(C)(6)/(7),(6)/(7),(2)/(7) (D) (-6)/(7),(-3)/(7),(2)/(7)

Write the set ,,{(1)/(2),(2)/(3),(3)/(4),(4)/(5),(5)/(6),(6)/(7)} in the setbuilder form.
