`(9)/(13)+(-8)/(13)+(4)/(3)+(-5)/(8)`

Re-arrange suitably and find the sum in each of the following: (3)/(5)+(7)/(3)+(9)/(5)+(-13)/(15)+(-7)/(3) (ii) (4)/(13)+(-5)/(8)+(-8)/(13)+(9)/(13)

Divide :(3)/(5)by(4)/(25) (ii) (-8)/(9)by(4)/(3)(-16)/(21)by(-4)/(3) (iv) (8)/(13)by(3)/(-26)

(-5)/(13)+?=-1 8/(13) (b) (-8)/(13) (-18)/(13) (d) (18)/(13)

(16(2)/(5)-12(1)/(15))-:3(4)/(81)=?( a) 1(9)/(19) (b) 1(9)/(13)(c)2(8)/(13) (d) 3(2)/(19) (e) None of these

Solve : ((-5)/(13) + ((-2))/( 13)) + ((- 3)/(8) + (18)/(20))

Simplify: 1/(1+(2/3)/(1+2/3+(8/9)/(1-2/3))) . (11)/(13) (b) (13)/(15) (c) (13)/(11) (d) (15)/(13)

(8)/(4)-(6)/(3)+(9)/(12)-:(15)/(13)

Evaluate each of the following: -2-(5)/(9)(ii)(-3)/(-8)-(-2)/(7) (iii) (-4)/(13)-(-5)/(26)

If the fractions (2)/(5),(3)/(8),(4)/(9),(5)/(13) and (6)/(11) are arranged ascending order of their values, which one will be the fourth? (2)/(5) (b) (3)/(8)(c)(4)/(9) (d) (5)/(13) (e) None of these
