If `a lt b` and `clt0`, then `(a)/(c)gt(b)/(c)`

If a gt b, " then " (a)/(c) lt (b)/(c) for all a, b and c in R , where c lt 0 . (True /False)

If a,b,c gt 0, then (a )/(b +c) = (b)/( c +a) = (a)/(a +b) = ?

If a,b,c gt 0, then (a )/(2a + b +c ) = (b)/(a + 2b +c)= (c )/(a +b + 2c) = ?

If a lt 0, b gt 0 and c lt 0 , then the point P(a, b, -c) lies in the octant

If a,b,c gt 0 then (a)/( a + b + c) = (b)/( a + b + c) = (c )/(a + b + c) = ?

If a lt 0, b gt 0 , then sqrt(a)sqrt(b) equal to

If f(x) is twice differentiable and continuous function in x in [a,b] also f'(x) gt 0 and f ''(x) lt 0 and c in (a,b) then (f(c) - f(a))/(f(b) - f(a)) is greater than

If a lt 0 and b gt 0 then the point (a, b) lies in quadrant

If a+c , a+b , b+c are in G.P and a,c,b are in H.P. where a , b , c gt 0 , then the value of (a+b)/(c ) is
