( (5)/(6)-:(6)/(7)times(6)/(7)-(8)/(9)-:1(3)/(5)+(3)/(4)times3(1)/(3)

(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

(5)(5)/(6)-3(8)/(9)-?=1

(5)/(6) -: (6)/(7) xx ? - (8)/(9) -: 1 (2)/(5) -: (3)/(4) xx 3 (1)/(3) = 2(7)/(9)

I : (2)/(1!)+(4)/(3!)+(6)/(5!)+....=e-1 II : (3)/(2!)+(5)/(4!)+(7)/(6!)+(9)/(8!)+....=e-1

5(5)/(6) -3(8)/(9) -? =1

Simplify (i) 2/3+5/6-1/9 (ii) 8-4 1/2-2 1/4 (iii) 8 5/6- 3 3/8+ 1 7/12

Let f= {(1, 5), (2, 6), (3, 4)} g = {(4, 7), (5,8), (6,9)}. Then gof is :

4.59xx 1.8-: 3.6 +5.4 of (1)/(9) - (1)/(5) = ?
