{:("Quantity A","Quantity B"),((1)/(4)-(1)/(5)+(1)/(6)-(1)/(7)+(1)/(8),(1)/(4)):}

Fill in the blanks substituting proper numbers: (i) (5)/(12)=(……….)/(6) (ii) (1)/(8)=(4)/(…….) (iii) (a)/(5)=(b)/(3)=(3a+5b)/(.........)

Evaluate {((1)/(3))^(-1)-((1)/(4))^(-1)}^(-1) (ii) ((5)/(8))^(-7)xx((8)/(5))^(-4)

If P(A) =(1)/(4),P(B) = (1)/(2),P(A uu B) = (5)/(8) , then P(A nn B) is equal to .

If P(A) =(1)/(4),P(B) = (1)/(2),P(A uu B) = (5)/(8) , then P(A nn B) is equal to .

Evaluate {(1/3)^(-1) -(1/4)^(-1)}^-1 (ii) (5/8)^(-7) xx (8/5)^(-4)

Show that the following sets of points are collinear.(2,5),(4,6) and (8,8)(b)(1,-1),(2,1) and (4,5)

Show that the following points are collinear: (i) A(2, -2), B(-3, 8) and C(-1, 4) (ii) A(-5, 1), B(5, 5) and C(10, 7) (iii) A(5, 1), B(1, -1) and C(11, 4) (iv) A(8, 1), B(3, -4) and C(2, -5)

If (4b^(2)+(1)/(b^(2)))=2, then (8b^(3)+(1)/(b^(3)))=? (a) 0 (b) 1 (c) 2 (d) 5

Verify (AB)^(-1)= B^(-1) A^(-1) for A = [(2,1),(5,3)] and B= [(4,5),(3,4)] .
