Multiply the following pairs of fractions: (a) "6(1)/(9),(1)/(8)," (b) "7(1)/(2),2(1)/(3)],[" (e) "(2)/(5),1(1)/(8)," (f) "(15)/(9),1(1)/(5)

Solve (i) 2-(3)/(5)(ii)4+(7)/(8)(iii)(3)/(5)+(2)/(7)(iv)(9)/(11)-(4)/(5)(v)(7)/(10)+(2)/(5)+(3)/(2)(vi)(2)(2)/(3)+(3)(1)/(2) (vii) (8)(1)/(2)-(3)(5)/(8)

2 (4)/(5) - 1 (3)/(8) + 3 (1)/(2) = ?

Simplify (i) {(1/3)^(-2) - (1/2)^(-3)} -: (1/4)^(-2). (ii) (5/8)^(-7) xx (8/5)^(-5).

(1)/(2)+(3)/(2).(1)/(4)+(5)/(3).(1)/(8)+(7)/(4).(1)/(16)+....=

Solve (i) 2 - 3/5 (ii) 4 + 7/8 (iii) 3/5 + 2/7 (iv) 9/11 - 4/5 (v) 7/10 + 2/5 + 3/2 (vi) (2) 2/3 + (3) 1/2 (vii) (8) 1/2 - (3) 5/8

If the expression 2(1)/(2) of (3)/(4)xx(1)/(2)-:(3)/(2)+(1)/(2)-:(3)/(2)[(2)/(3)-(1)/(2) of (2)/(3)] is simplified,we get (a) (1)/(2) (b) (7)/(8)(c)1(5)/(8) (d) 2(3)/(5)

Using determinants show that the following points are collinear: (i) (3, -2), (8, 8) and (5, 2) (ii) (2, 3), (-1, -2) and (5, 8)
