`(6)/(3)+(7)/(2)+(9)/(4)`

Express the following as improper fractions: (a) (7)(3)/(4) (b) (5)(6)/(7) (c) (2)(5)/(6) (d) (10)(3)/(5) (e) (9) (3)/(7) (f) (8)(9)/(4)

(5)/(6)-:(6)/(7)xx?-(8)/(9)-:1(3)/(5)+(3)/(4)xx3(1)/(3)=2(7)/(9)(7)/(6)(b)(6)/(7)(c)1(d) None of these

The value of (1)/(3)-:(6)/(7)-:(6)/(3)+(8)/(9)-(2)/(3)times(4)/(3) is:

If the curves y^(2)=6x,9x^(2)+by^(2)=16 intersect each other at right angles then the value of b is: (1)6(2)(7)/(2)(3)4(4)(9)/(2)

(3)/(2!)+(5)/(4!)+(7)/(6!)+(9)/(8!)+....=

Find :(i)(7)/(3)-:2(ii)(4)/(9)-:5(iii)(6)/(13)-:7(iv) (4) (1)/(3)-:3(v)(3)(1)/(2)-:4(vi)(4)(3)/(7)-:7

If the curves y^2=6x , 9x^2+by^2=16 intersect each other at right angles then the value of b is: (1) 6 (2) 7/2 (3) 4 (4) 9/2
